Standard Specification for High Hardenability Antifriction Bearing Steel
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers high hardenability modifications of high-carbon bearing quality steel to be used in the manufacture of antifriction bearings. The grades of steels covered here are: Grade 1, Grade 2, Grade 3, Grade 4, Grade B2, Grade B3, Grade B4, Grade B5, Grade B6, Grade B7, and Grade B8. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, titanium, copper, molybdenum, oxygen, and aluminum. The steels shall undergo normalizing followed by spheroidize annealing before heating for end quenching. Test for hardenability shall be performed wherein specimens shall conform to required Brinell and Rockwell hardness.
Scope
1.1 This specification covers high hardenability modifications of high-carbon bearing quality steel to be used in the manufacture of antifriction 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.
