OK 14MnNi

Austenitic manganese steel electrode with nickel for surfacing and building up mangnese steel components exposed to severe impact and moderate abrasion. The weld metal is less prone to embrittlement and cracking compared to plain austenitic manganese steel weld metal. It workhardens under compressive stresses. Applications include: crusher plates and rolls, cones and mantels of rotary crushers, rail points. The interpass temperature should be kept as low as possible.
