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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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.
