Postalloy® DuraBuild™ 2893-MCG

Postalloy® DuraBuild™ 2893-MCG is a medium hardness, machinable gas-shielded hardfacing and build-up wire. It provides high compressive strengths and the wear life will far exceed conventional build-up alloys and mild steel. Weld deposits are exceptionally sound and dense, and heavy build-ups are possible. Preheat may be necessary for certain low alloy, higher carbon steels. Use on carbon and alloy steels.
