Postalloy® DuraForge™ 2235-FCG
Postalloy® DuraForge™ 2235-FCG is a flux-cored gas-shielded welding alloy that produces a tough impact resistant nickel-chromium-moly weld deposit. DuraForge™ 2235-FCG has good metal-to-metal wear properties at low and high temperatures. DuraForge™ 2235-FCG is commonly used in the forging industry for building up and repairing sow blocks, rams, die shanks, die holders or filling in complete impressions as required. DuraForge™ 2235-FCG has a self-releasing synthetic slag that allows it to be used at many different amperage/voltage settings. DuraForge™ 2235-FCG operates well at high amperage/voltage settings when high deposition rates are required. It also has a very stable arc and fast freezing slag when used at low amperage/volt settings.

Welding Parameters
Current Type: DC Electrode Positive
| Volts | Amps | Diameter | Stick Out |
|---|---|---|---|
| 25-29 | 200-300 | 1/16" (1.6mm) | 1" (25mm) |
| 26-32 | 250-450 | 3/32" (2.4mm) | 1¼" (32mm) |

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.
