Postalloy® DuraForgeā„¢
PostalloyĀ® DuraForgeā„¢ 2756-FCG is a modified 5% chrome-tungsten-moly-vanadium enriched welding alloy. Due to additional moly and vanadium, DuraForgeā„¢ 2756-FCG is more wear resistant than PostalloyĀ® DuraForgeā„¢ 2755-FCG. Used to upgrade standard AISI H-12 hot-working tool steels. Water spray coolants should be avoided.

Typical Applications:
Primarily used to repair and rebuild flash lines on press forging dies and is also used to overlay shallow impression dies. Use PostalloyĀ® DuraForgeā„¢ 2747-FCG as an intermediate build-up on deeper impressions. A 3/8" overlay would be the maximum.

Welding Procedure

Shielding Gas:75/25 Argon/CO2, 80/20 Argon/CO2, 90/10 Argon/CO2, 92/8 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.
