Also known as high temperature bearing steel. With the addition of strong carbide forming elements such as W, Mo, Cr and V, stable alloy carbide can be precipitated to produce secondary hardening after tempering at a temperature above 500 ° C, so that bearing steel with high temperature hardness, high temperature wear resistance, high temperature contact fatigue strength, oxidation resistance and high temperature dimensional stability can be made in high temperature environment.
