285-MCG (formerly part 285-SPL)
POSTALLOY® 285-MCG is a non-cracking high alloy austenitic manganese steel metal-cored, gas-shielded welding wire for joining, build-up or hardfacing.
  • Produces high-strength, crack-free deposits that are tough, ductile and work-harden rapidly.

  • The high yield strength reduces mushrooming from impact.

  • Unlike common manganese alloys, which should not be used for welding plain carbon steel.

  • POSTALLOY® 285-MCG can be used with full confidence to build-up or join manganese steels as well as manganese to carbon and low alloy steels.
