Characteristics and scope of application:
SCM420 alloy steel pipe is generally used in the quenching and tempering or carburizing and quenching state. It is used to manufacture high-pressure pipes and various fasteners and relatively high pressure pipes that work in non-corrosive media and media with operating temperatures below 250°C and containing nitrogen and hydrogen mixtures. Advanced carburized parts such as gears, shafts, etc.
