Postalloy® DuraForge™ 2225-FCG

Postalloy® DuraForge 2225-FCG is an iron base flux-cored welding alloy that produces a wear resistant nickel-chromium-moly weld deposit for build-up and welding wrought and cast steel. DuraForge 2225-FCG is optimally suited for forging die applications, primarily for the repair and reclamation of hammer dies. The welding characteristics facilitate continuous multiple passes without pausing for slag removal. It is also excellent as a maintenance alloy, providing 130,000 psi tensile strength fabricating welds. Preferred for use on forging hammer bases, columns, rams, sow blocks, die shanks and die holders.

Welding Procedure:

Gas Cover Options (for all wire sizes):

75/25 Argon/CO2, 80/20 Argon/CO2, 90/10 Argon/CO2, 98/2 Argon/CO2.
Slow Cooling after welding is extremely important to reduce stress build-up and minimize the risk of cracking. Therefore, using this wire requires a minimum of preheat from 600-800 °F (315-427 °C) depending on size of the part and composition of the base metal. Throughout welding operation, limit interpass temperature to 900 °F (480 °C). After welding, the part should be returned to the preheat furnace to allow the temperature throughout the part to equalize.
