Postalloy® DuraForgeā„¢
PostalloyĀ®  DuraForgeā„¢2235-FCG is a flux-cored gas-shielded welding alloy that produces a tough impact resistant nickel-chromium-moly weld deposit. DuraForgeā„¢ 2235-FCG has good metal-to-metal wear properties at low and high temperatures. DuraForgeā„¢ 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. DuraForgeā„¢2235-FCG has a self-releasing synthetic slag that allows it to be used at many different amperage/voltage settings. DuraForgeā„¢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 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 600Ā°F to 800Ā°F (315Ā°C to 427Ā°C) depending on size of the part and composition of the base metal.  Throughout welding operation, limit interpass temperature to 900Ā°F (480Ā°C).  After welding, the part should be returned to the preheat furnace to allow the temperature throughout the part to equalize.
