.Characteristics and scope of application:
High hardenability, no tempering, brittleness, very good weldability, little tendency to form cold cracks Good machinability and cold strain plasticity. It is generally used in the quenching and tempering or carburizing and quenching state to manufacture high-pressure pipes and various fasteners and higher-grade carburized parts that work in non-corrosive media and media with operating temperatures below ℃ and containing nitrogen and hydrogen mixtures. Such as gears, shafts, etc. .Mechanical properties:
