SMnC420 with moderate intensity,low temperature performance is good, compared with the corresponding carbon content of the carbon steel and its high hardenability. SMnC420 Generally used as a small section of part and carburizing small gear, shaft, steel sleeve, piston pin, diesel engine sleeve, car steering roller shaft, valve plunger, etc; Also can be used for quenched and tempered steel, such as cold heading bolt or larger section of conditioning parts.
