Postalloy® DuraHard™ 2894-MCG

Postalloy® DuraHard™ 2894-MCG is a non-cracking medium chromium gas-shielded hardfacing overlay designed for applications that require good corrosion, metal-to-metal wear and good abrasion resistance, but a crack-free weld deposit. It can be applied to carbon and alloy steels, and stainless steels.
