Postalloy® 301-FCG
Postalloy® 301-FCG is a high strength, crack resistant flux-cored, gas-shielded all-position welding alloy specifically designed for welding problem steels such as low alloy, high carbon or crack sensitive tool steels. Ideal for welding dissimilar steels - low alloy, spring steels, carbon steels, tool steels. The benefits of Postalloy® 301-FCG include:
- Excellent joining characteristics - With the combination of balanced alloy chemistry and high strength, crack resistant weld deposits, the capability to weld dissimilar problem steels is outstanding.
- Carbon has no adverse effects - Carbon, the cause of most problems associated with weld cracking and hard spots, is rendered harmless.
- Acts as a shock absorber during operation - Since Postalloy® 301-FCG does not respond to heat-treatment and remains ductile, it has the ability to withstand heavy impact or shock loading.
