POSTALLOY® 2850-FCO
Work-hardening austenitic manganese flux-cored wire, alloyed with chromium and nickel for improved weld deposit properties over standard manganese alloys.
It is designed for build-up, hardfacing and fabricating of manganese steel.
Deposits are very tough, and work-harden rapidly in-service as plastic deformation occurs during impact.

Out-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.
