Postalloy® Durachrome-G

A premium metal-cored, gas-shielded chromium carbide hardfacing alloy that has a high volume fraction of carbides dispersed in a hard matrix. Excellent out-of-position weldability. For applications involving high abrasion and mild or moderate impact. Deposit polish in service and are heat resistant to 1000°F (538°C). Use on carbon and low alloy steels. When used with 100% CO2 or 75/25 Argon/CO, it offers excellent weldability in flat, horizontal and vertical down positions, the arc is very stable at both high and low voltages settings, and the smoke level is very low.
