2893-FCO
Description
POSTALLOY® 2893-FCO is a medium hardness, machinable flux-cored, open-arc 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 required on certain carbon and low alloy steels.
