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.

Welding ProcedureOut-of-position - When welding out-of-position it is best to use a shielding gas of 100% CO2 at 40-45 cfh and DC Straight Polarity. Welding should proceed vertical-down with 1" wide weave beads.
