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.
