Description

Technical Field

[0002] Die steel is a type of steel used to make cold stamping dies, hot forging dies, die casting dies and other dies. Dies are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the die directly affects the quality of the pressure processing process, the precision output of the product and the production cost. The quality and service life of the die are mainly affected by the die material and heat treatment in addition to reasonable structural design and processing accuracy.

[0003] The purpose of quenching is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then temper it at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools. Quenching can also be used to meet the special physical and chemical properties of some special steels such as ferromagnetism and corrosion resistance.
