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.
