POSTALLOY 2893-SPL is a high hardness, machinable gas-shielded hardfacing 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 without danger of cracking (preheat may be necessary for certain low alloy, higher carbon steels). Use on carbon and alloy steels.
