Postalloy® DuraBuild™ 2890-FCO

Postalloy® DuraBuild™ 2890-FCO is a tough, build-up welding wire that can be applied to carbon and low alloy steels. Weld deposits are exceptionally sound and dense. Heavy buildups are possible prior to overlaying with a more wear resistant hardfacing alloy. DuraBuild™ 2890-FCO provides a tough machinable deposit. Unlimited layers can be applied with proper procedures, preheat and inter-pass temperatures.
