For intermetallic abrasion, hardfacing of fans, upper rollers and sprockets.

Machining is possible, in general. Hardness increases by quenching after machining. It is suitable for intermetallic abrasion and moderate impact abrasion.

① Preheating is unnecessary, in general, large weldments of hardening property should be preheated.
② In case of high cooling speed, preheat or postheat to prevent difficulty of machining caused by hardening.
③ Pay attention to blow hole at the arc starting.
④ Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
