Anotation

This specification covers the powder forged ferrous materials fabricated by hot densification of atomized prealloyed or iron powders and intended for use as structural parts. The strcutural parts shall be made by hot forging of powder metallurgy preforms in confined dies with or without subsequent heat treatment. The materials shall conform to the required chemical composition for nickel, molybdenum, manganese, copper, chromium, sulfur, silicon, phosphorus, carbon, and oxygen. The mechanical properties such as yield strength, elongation, Rockwell hardness, impact energy, compressive yield strength and fatigue shal be determined using the tensile test method, Charpy V-notch impact energy test method, and hardness test method. The materials shall conform to the required surface finger oxide penetration, interparticle oxide networks, decarburization depth, and nonmetallic inclusion level.
