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

Current Type : DC Electrode Positive
|30-31||300-310||1/16" (1.6mm)||1“ (25mm)|

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 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.
