Hardfacing Electrodes
SUPER-Mn/Ni
AWS: SFA 5.13 EFeMn-A
EN ISO CODE:
Super-Mn/Ni is basic coated electrode depositing high manganese weld metal for resurfacing austenitic manganese steels. Austenitic manganese, work hardening weld metal having excellent wear resistance under impact and abrasion. The weld metal possesses exceptional toughness and work hardens under impact. It is ideally suited for resurfacing to obtain wear resistance against impact, abrasion and a combination of both. The typical applications include rock crushing jaws, manganese steel castings, rail frogs & switches, crusher jaws & hammers, rail crossovers, etc.
