ASTM A485 PDF

ASTM A Abstract This specification covers high hardenability modifications of high-carbon bearing quality steel to be used in the manufacture of antifriction bearings. 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.
