1: Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require surface wear resistance (such as gears, rolls, carburized parts, etc.).
2: Through quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different usage requirements.
3: In addition, quenching can also enable some special properties of steel to obtain certain physical and chemical properties, such as quenching to enhance the ferromagnetism of permanent magnet steel, and stainless steel to improve its corrosion resistance.
