Ancorsteel 721 SH is a water atomized, prealloyed steel powder specifically developed for sinter hardenings. In the powder production process used to make Ancorsteel, molten steel is atomized into irregular, homogeneous particles which are then annealed to produce uniform, dependable steel powders. Ancorsteel grades are designed for powder metal parts requiring densities exceeding 6.7 g/cm^3 (0.24 lb/in.^3). This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on powder metal forms. Filing Code: CS-155.
