A756 - 09
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.
