2893-MCG (formerly part 2893-SPL)
POSTALLOY® 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 buildups are possible. Preheat may be necessary for certain low alloy, higher carbon steels. Use on carbon and alloy steels.
