Quenching process of steel nails are steel nails to be heated to the appropriate temperature and a specific period of time, followed by Quick cooling dip quenching medium. Quenching method commonly used is salt, water, oil, air, etc. Quenching can effectively improve the hardness and wear resistance of the metal, so widely used in a variety of engineering, mould, and by requiring the wear-resistant surface parts (carburizing parts such as gears, rollers, etc).
Steel nail hardening treatment, rigid better, stronger penetrating power. Make it high strength, hardness, and can be nailed into the concrete and other hard materials, so are most widely used.
