Abstract AISI 1095 is a high-carbon, water-hardening tool and spring steel of low hardenability. Depending on the properties required, it may be used in the astrolled, annealed, normalized or liquid-quenched-and-tempered condition. It is hardened by austenitizing and quenching in water (preferably) but it may be quenched in oil if a less drastic quench meets requirements. Its many uses include springs, bushings, drills, hay-rake teeth, pins and ball bearings. 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, and joining. Filing Code: CS-99. Producer or source: Carbon steel mills.
