This specification covers normalized and tempered carbon steel, and liquid quenched and tempered alloy steel forgings for pinions, gears, and shafts for reduction gears. Prior to heat treatment for mechanical properties testing , steel materials may undergo machining and boring, after which specimens shall be stress relieved. Tensile, impact and Brinell hardness tests shall be performed wherein forgings shall conform to the following mechanical properties: tensile strength, yield strength, elongation, reduction of area, Charpy V-notch, and Brinell hardness. Specimens shall also conform to chemical requirements for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, vanadium, copper, and aluminum.
