Postalloy® DuraMang™ 285-FCO

Postalloy® DuraMang™ 285-FCO is a non-cracking high alloy austenitic manganese steel flux-cored, 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-FCO can be used with full confidence to build-up or join manganese steels, as well as manganese to carbon and low alloy steels.

Welding Parameters

Current Type: DC Electrode Positive

Volts Amps Diameter Stick Out
21-27 100-200 .045" (1.2mm) 3/4"-1¼"(19-32mm)
23-28 150-300 1/16" (1.6mm) 1"-1½"(25-38mm)
23-30 200-450 7/64" (2.8mm) 1½" (38mm)

Welding Procedure:

If a gas cover is desirable , use 100% CO at 40-45 cfh. This will cause amperages to go up by about 10%. The stick out should be shortened. When welding out-of-position, use the lower ranges of voltages and amperages.
