ASTM, AISI, SAE bearing steel grades

Bearing steel is the steel used to make ball bearings, rollers and bearing rings. Bearing steel needs to have high hardness, wear-resistance and elastic limit because the bearing is under great pressure and friction when working, so the uniform chemical composition, strict non-metallic inclusion, carbide content and distribution are required, and it is one of…

What Is Carburized Steel？

What is carburized steel？ The steel used to make carburized parts is referred as carburized carbon steel. Carburizing is the heat treatment process of quenching after carburizing atoms to the surface of steel parts. Carbon infiltration can significantly improve the wear resistance, durability, toughness and other properties of steel parts. Carburized carbon steel is generally after carburizing…
