The Role Of Cold-drawn Bearing Steel
Jan 15, 2025
The role of cold-drawn bearing steel mainly includes improving strength, hardness and wear resistance, improving surface quality and dimensional stability. Cold drawing is a manufacturing process that reduces the cross-sectional area of steel by drawing at room temperature. Bearing steel after cold drawing has the following specific effects:
Improve strength and hardness: The yield strength, tensile strength and hardness of cold-drawn bearing steel are all improved, which makes the bearing steel perform better under heavy load and high temperature environment.
The specific application scope of the cold drawing process includes the manufacture of various steel products, such as cold-drawn steel wire, cold-drawn steel pipe, gear shaft, transmission shaft and other precision parts, as well as a large number of industrial products such as locomotive wheels, pencil leads, wires, cables, etc. In addition, the cold drawing process is also widely used in the manufacture of various special steels and alloy materials, such as high-speed steel, stainless steel, titanium alloy, etc.
