SAE 1522 is a low-carbon steel that combines good workability, good machinability and good weldability. It is used in the hot-rolled, annealed, normalized or water-quenched-and-tempered condition for a variety of applications. It also is used for parts case-hardened by carburizing. It has a relatively high manganese content (1.10-1.40%); this provides increased hardenability which is reflected in all uses and gives increased strength and hardness in the core of carburized parts and in sections and components that have not been carburized. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-87. Producer or source: Carbon steel mills.
