Description
Gyrator Crusher
Gyrator Crusher
Postalloy®  DuraMang™ 2850-FCO is a work-hardening austenitic manganese flux-cored, open-arc wire, alloyed with chromium and nickel for improved weld deposit properties over standard manganese alloys. It is designed for buildup, hardfacing and fabricating of manganese steel. Deposits are very tough, and work-harden rapidly in service as plastic deformation occurs during impact.
