UNS G10210 is a carbon steel of relatively high manganese content which increases hardenability and hardness over that of carbon steels of lower manganese. It combines good machinability, good workability (hot or cold) and good weldability. It is used in the annealed, hot-worked, normalized, cold-worked or water-quenched-and-tempered condition for many applications. It may be used in uncarburized applications and for components case-hardened by carburizing. 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-122. Producer or source: Carbon steel mills.

Lucefin C20 is a low-carbon, non-alloy steel that is used in the normalized, cold finished, or quenched and tempered condition. It 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 with little need for increased mechanical properties in the core. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: CS-209. Producer or source: Lucefin S.p.A..

1021, 1022, C20C, and C20GC are wrought low-carbon non-alloy steels that are used in the as rolled, normalized, cold worked, or quenched and tempered condition. They 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 ductility, good cold formability, and good weldability are required. 1021 and 1022 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 with little need for increased mechanical properties in the core. 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-223. Producer or source: Data Survey.

1021, 1022, C20C, and C20GC are wrought low-carbon (carbon = 0.18–0.23%) non-alloy steels that are used in the as rolled, normalized, cold worked, or quenched and tempered condition. They 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 ductility, good cold formability, and good weldability are required. 1021 and 1022 may also be used in the case hardened, nitrided, or nitrocarburized condition. This datasheet provides information on composition, physical properties, microstructure, hardness, and tensile properties. It also includes information on forming and heat treating.
