Postalloy® DuraForgeā„¢
2755-FCG
Description
PostalloyĀ® DuraForgeā„¢ 2755-FCG is an iron base chromium-moly-tungsten-vanadium hot-work tool steel. It resists wear from shock, heat-checking, scaling and erosion at high temperatures. It is heat-treatable and has very good dimensional stability. In addition, when used for "cold" cutting, shearing and trimming applications, weld deposits have excellent resistance to chipping.

Typical Applications:
For the repair and reclamation of AISI H-12 hot-work tool steel. Water spray coolants should be avoided.
Forging dies, up-setter and coining dies, gripper and header dies, hot-forming dies, trimmer and punches, shear blades and knives, extrusion mandrels and tong bits.

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.
