ASM CS-262 PDF

1020, C20E2C, and C22 are wrought low-carbon (carbon = 0.17–0.24%) non-alloy steels that are used in the as-rolled, normalized, cold worked condition, 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-medium strength, good cold formability, and excellent weldability are required. These steels may also be used in the case hardened, nitrided, or nitrocarburized condition.
