Description
This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of February 1998. It is recommended, therefore, that this specification not be specified for new designs. “NONCURRENT” refers to those materials which have previously been widely used and which may be required on some existing designs in the future. The Aerospace Materials Division, however, does not recommend these as standard materials for future use in new designs.This specification covers procedures for approval of premium-quality forgings, usually serialized, the stock from which such forgings are produced, and the controls to be exercised in producing the forgings and forging stock. This procedure has been used typically for highly-stressed parts produced from forgings which require approval of the forgings and the stock from which they are made and facets of their production to ensure that production lots of forgings are of the same metallurgical quality and are produced by the same basic procedures as the forgings and stock originally qualified, but usage is not limited to such applications. This specification is applicable to parts made of steels and heat-treatable corrosion and heat resistant steels and which are subjected to rigid inspection standards throughout manufacture from ingot to finished part.
