Generally, in china, we usually use fully-hardenability heat treatment,that is,entire inductive heating-surface quenching heat treatment, to make the surface of the material high hardness and abrasive resistance of fully quenching high-carbon chromium bearing steel,and to make the core high toughness and good impact propriety.
Applications:
1,Mainly used for manufacturing ordinary rolling bearing ring.
2,other applications such as used for automotive industry and bearings in rotating machinery.
Competitive Advantage:
Huacheng Pipe Making Company is one of the largest seamless steel pipe manufacturers in China.We’ve passed API 5L,API 5CT, PED, BV, TUV certification and ISO quality system certification.With good quality and competitive price, we believe we could be your reliable supplier.
