Postalloy® DuraForge™ 2752-FCG

Postalloy® DuraForge™ 2752-FCG is a modified chrome-nickel-moly-vanadium-tungsten hot-work tool steel welding alloy with very good resistance to softening and fatigue at high temperatures. The high chromium content promotes very good oxidation resistance at high temperatures.

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.
