OK 86.08
SMAW
Type Basic

OK 86.08 deposits an austenitic manganese steel alloy which work-hardens under impact and compressive stresses. The electrode is primarily used for surfacing and building up manganese steel components such as crusher, jaws and hammers. The interpass temperature should be kept as low as possible.
