Hardfacing Electrodes
Super-Mn
AWS: SFA
EN ISO CODE:
Super-Mn is an electrode depositing high manganese steel weld metal. The weld metal possesses excellent toughness and work hardens under impact. The deposit exhibits an austenitic structure and is ideally suited for re-surfacing austenitic manganese steel components like crusher jaws, hammers, etc. for resistance against wear by impact and abrasion.
