Historical (view previous versions of standard)
This specification covers stainless steel bars for compressor and turbine bucket, blade, and airfoil applications. Materials shall be produced by basic electric furnace melting process with argon-oxygen-decarburization refining or by vacuum ladle degassing. Electro-slag remelting shall also be conducted unless otherwise specified by the purchaser. Two complete heat treatments, consisting of an austenize, quench, and temper, shall be conducted. Straightening, stress relieving, and water or oil quenching shall be executed as well. Steel bars shall adhere to chemical composition and mechanical property requirements, including tensile strength, yield strength, elongation, reduction of area, impact strength, and Brinell hardness.
