SAE 1020, CEN C20, CEN C22, ISO C20

Abstract

Abstract 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. This datasheet provides information on composition, physical properties, microstructure, hardness, and tensile properties. It also includes information on forming and heat treating.
