Standard Specification for High-Carbon Anti-Friction Bearing Steel
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers high-carbon bearing-quality steel to be used in the manufacture of anti-friction bearings. Materials shall conform to chemical compositions as specified herein, and to physical size and shape as agreed upon between the manufacturer and purchaser. Steels shall exhibit fine fracture grain size when quenched from normal austenitizing temperatures. Decarburization and surface imperfections shall not exceed the limits also specified herein. When annealing is specified in the order, the steel shall adhere to hardness requirements and have a completely spheroidized microstructure, which shall accordingly be rated and reported as carbide size, carbide network, and lamellar content.
Scope
1.1 This specification covers high-carbon bearing-quality steel to be used in the manufacture of anti-friction bearings.
1.2 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
