This specification deals with the requirements for chromium-carbon bearing quality stainless steel to be used in the manufacture of anti-friction bearings. Chemical requirements shall conform to the required compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, and molybdenum. Heat analysis and product analysis shall made. Decarburization and surface imperfection limits are specified. When annealing will be made, the steel should have a completely spheroidized microstructure and the hardness is specified.

1.1 This specification covers the requirements for chromium-carbon bearing quality stainless 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 inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
