Quench Hardening Steel

Quench hardening is a heat-treatment process in which steel and cast iron alloys are strengthened and hardened. This is done by heating the material to a certain temperature, depending on the material. This produces a harder material by either surface hardening or through-hardening varying on the rate at which the material is cooled. The material is then often tempered to reduce the brittleness that may increase from the quench hardening process. Items that may be quenched include gears, shafts, wear-resistant blocks, bolts, and mechanical parts in automobiles.

Bearing steel is a kind of steel used to manufacture balls, rollers and sleeves of rolling bearings. It can also be used to make precision measuring tools, cold punching dies, machine tool screws, such as punching dies, measuring tools, taps and precision accessories for diesel oil pumps. Bearing steel is the steel used to make balls, rollers, and bearing rings.
