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.
