Postalloy® DuraForgeā„¢
2752-FCG
Description
PostalloyĀ® DuraForgeā„¢ 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.

Typical Application:
Frequently used as an overlay or capping layer on top of DuraForgeā„¢ 2747-FCG. Used for the welding of medium to shallow hammer dies and most any type of press dies. It is often used in connecting rods, crankshafts and yokes. It is good for intricate impressions that require high strength and good wear resistance.

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.
