รายละเอียดเอกสาร

This specification covers stainless steel forgings for compressor and turbine bucket, blade, and airfoil applications. The stainless steel shall be made by the melting process and either the closed impression die or the open die forging processes may be utilized. Two complete heat treatments, consisting of an austenize, quench, and temper, are permitted. When heat treatment for mechanical properties is followed by straightening, a stress-relieving heat treatment is required. The forgings shall be subjected to tension, impact, hardness, and non-destructive tests. All forgings shall be free of cracks, seams, laps, shrinkage, and similar discontinuities.
