| Item | Bearing steel |
| Introduction | Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, and high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel grades in all steel production. In 1976, the International Organization for Standardization ISO incorporated some general bearing steel numbers into international standards, and divided the bearing steel into four categories: fully hardened bearing steel, surface hardened bearing steel, stainless bearing steel, high temperature bearing steel, and a total of 17 categories Steel number. |
