Purpose: 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. Application: This procedure has been used typically for highly-stressed parts produced from forgings which require approval ofthe forgings and the stock from which they are made and facets of theirproduction 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. Thisspecification is applicable to partsmade of steels and heat-treatable corrosion and heat resistant alloys and which are subjected to rigid inspection standards throughout manufacture from ingot to finished part.
