                              Postalloy Wire: Metal-cored, open-arc wire with smooth weld ability.
                              Deposits are slag-free.
                              Postalloy® PS-150 is a tubular metal-cored hardfacing wire that provides a dense, heterogeneous deposit of vanadium - tungsten carbides, along with other elements to enhance wear resistance, resulting in a very good combination of abrasion and impact resistance that is superior to chromium carbide hardfacing alloys. Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                              Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

                                    Postalloy Flux-coated Tubular Electrode POSTALLOY® 216HD (Chapisco), for Roll-Arcing, is primarily engineered for the sugar cane industry and is to be used while the sugar cane roll is rotating. Postalloy® 216HD produces a rough weld deposit that will aid in pulling, tearing and crushing the sugar cane as it feeds through the rolls during processing. Also used for sugar mill rolls hooks (Picote).

                                    Postalloy® 216HD is a chromium carbide tubular hardfacing electrode with much higher percentages of carbide forming elements contained in the core than with conventional flux-coated electrodes. It's tubular construction allows it to be used at higher deposition rates and much lower current settings than traditional flux-coated electrodes. 1/4" (6.0mm) is used around 100 amps. Weld chemistry produces a chromium carbide weld deposit for overlaying surfaces exposed to high abrasion and medium impact.

                                            Deposits are slag-free.
                                            Postalloy® PS-150 is a tubular metal-cored hardfacing wire that provides a dense, heterogeneous deposit of vanadium - tungsten carbides, along with other elements to enhance wear resistance, resulting in a very good combination of abrasion and impact resistance that is superior to chromium carbide hardfacing alloys. Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                            Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

This alloy may also be used at elevated temperatures up to 1500°F (816°C). First pass hardness is greater than other hardface electrodes - 65Rc on mild steel. Other outstanding features include:
                                                     • Easy out-of-position weldability with the 1/4" diameter
                                                     • Excellent AC or DC operation, even on a "buzz box"
                                                     • Low amperage and high metal recovery - no slag to chip
                                                     • High deposition rates - up to 3 times faster than ordinary electrodes

                                                              Postalloy® PS-150 is a tubular metal-cored hardfacing wire that provides a dense, heterogeneous deposit of vanadium - tungsten carbides, along with other elements to enhance wear resistance, resulting in a very good combination of abrasion and impact resistance that is superior to chromium carbide hardfacing alloys. Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                              Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt.

It can be used equally well for joining and buildup/surfacing of carbon, low alloy and manganese steels. Weld deposits made with POSTALLOY® 207 are a modified chromium-manganese chemistry providing an excellent combination of weld metal strength and ductility. Work-hardens rapidly under repeated impact. The yield strength is higher than ordinary manganese alloys providing greater resistance to mushrooming when subjected to compressive loads and repeated impact. Ideal as a cushioning or buffer layer on manganese steel parts that must be rebuilt on a repetitive basis. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation.

It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation. Pulverizing hammers

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                            Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

                                                                                                                                                                                           • Excellent joining characteristics - With the combination of balanced alloy chemistry and high strength, crack resistant weld deposits, the capability to weld dissimilar problem steels is outstanding.
                                                                                                                                                                                           • Carbon has no adverse effects - Carbon, the cause of most problems associated with weld cracking and hard spots, is rendered harmless.
                                                                                                                                                                                           • Acts as a shock absorber during operation - Since POSTALLOY® 301 does not respond to heat-treatment and remains ductile, it has the ability to withstand heavy impact or shock loading.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                    Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

                                                                                                                                                                                                          Postalloy® PS-150 is a tubular metal-cored hardfacing wire that provides a dense, heterogeneous deposit of vanadium - tungsten carbides, along with other elements to enhance wear resistance, resulting in a very good combination of abrasion and impact resistance that is superior to chromium carbide hardfacing alloys. Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                          Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

It is primarily used as a matrix alloy for the MIG Carbide Embedding Process and will consistently provide an even distribution of carbide particles throughout the entire weld deposit. Hardness range is 55-60 HRC. Unlike soft metal steel welding wires which are commonly used with the MIG Carbide Embedding Process, the high hardness tool steel microstructure of POSTALLOY® PS-98 is designed to encapsulate and protect the carbide particles from premature erosion.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                      Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                  Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                      Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                                  Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                                                              Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

Postalloy®2898-SPL is a general purpose self-hardening overlay with a good combination of resistance to abrasion and impact. POSTALLOY® 2898-SPL is very tough with excellent resistance to chipping and spalling. Deposits will retain their hardness and maintain a good cutting edge up to 1100°F (593°C). For maximum impact resistance and to avoid cracking in multi-layer deposits, a preheat of 550°F (288°C) is recommended.

The microstructure has very fine carbides which give improved wear, errosion and impact resistance over traditional Chromium Carbides. It is designed for applications that require more abrasion resistance than POSTALLOY® 215HD. The Carbide concentration is denser and slightly harder but less brittle than POSTALLOY® 215HD providing a better, more wear-resistant surface.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                                                                              Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation.

Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical.

                                                                                                                                                                                                                                                                                                                              Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy® PS-150 is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.

It maintains its hardness and wear resistance up to 1400°F (760°C). The chemistry is highly tolerant of dilution. One layer will easily outwear two layers of ordinary chrome carbides and in some applications the wear is equal to tungsten carbide. Use on low carbon mild steel, manganese, stainless, and low alloy steels.

It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation.

It produces a very smooth weld deposit with improved impact resistance over pure Tungsten Carbide. The unique blend of Tungsten Carbide in a Chromium rich matrix also provides some corrosion protection but primarily helps to provide a high polish in service to reduce the coeffcient of friction. When protection against severe abrasion, with limited impact, is needed, POSTALLOY® 220HD is an ideal choice.
