Postalloy® DuraBuild™ 2892-MCG

Postalloy® DuraBuild™ 2892-MCG is a medium hard build-up welding wire with excellent compressive strength. It is recommended for applications where weld deposits must offer good metal-to-metal wear resistance, while remaining machinable “as welded”. Use on carbon and low alloy steels.
