AISI 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; 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-111. Producer or source: Carbon steel mills.

1020, C22, C22E, and C22R are wrought low-carbon non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. These steels are widely used for lightly and moderately stressed parts that require higher strength levels than can be achieved by the lower carbon grades, and also for applications where a combination of low-to-moderate strength, good toughness, good cold formability, and good weldability are required. They may also be used in the carburized or carbonitrided, and subsequently quench hardened and tempered condition for parts requiring a hard, wear-resistant surface, but where the core strength is not critical. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CS-222. Producer or source: Data Survey.
