Postalloy® DuraMang™ 285-MCG
Postalloy® DuraMang™285-MCG is a non-cracking high alloy austenitic manganese steel metal-cored, gas-shielded welding wire for joining, build-up or hardfacing. Produces high-strength, crack-free deposits that are tough, ductile and work harden rapidly. Work-hardens faster than DuraMang™ 2850-FCO. The high yield strength reduces mushrooming from impact. Unlike common manganese alloys, which should not be used for welding plain carbon steel DuraMang™ 285-MCG can be used with full confidence to build-up or join manganese steels as well as manganese to carbon and low alloy steels.
