ASTM A534-17

Standard Specification for Carburizing Steels for Anti-Friction Bearings

ABSTRACT
This specification covers standards for carburizing steels to be used in anti-friction bearings. Materials shall conform to carbon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, copper, oxygen, and aluminum contents. Materials shall adhere to inclusion ratings set for thin and heavy series. Grain size and hardenability requirements shall be followed. Decarburization and surface imperfections of hot-rolled, cold-finished, or annealed bars and tubes shall not exceed specified limits as measured through microscopical methods.
SCOPE
1.1 This specification covers the requirements for carburizing 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 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.
