Postalloy® DuraMang™ 2965-SA

Postalloy® DuraMang 2965-SA is a submerged arc hardfacing wire that deposits fully austenitic chromium-manganese weld metal. It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation.
