die steel
Die steel is a kind of steel used to make cold dies, hot forging dies, die casting dies and other dies. Mould is the main processing tool for manufacturing parts in machinery manufacturing, radio instruments, motors, electrical appliances and other industrial sectors.
Properties of die steel		Should have high hardness, Strength, Wear resistance, Enough toughness, And high hardenability, Hardening capacity and other process properties.
Classification of die steel		It can be divided into three types: cold-rolled die steel, hot-rolled die steel and plastic die steel, which are used for forging, stamping, cutting and die casting. Because of the different uses and complicated working conditions of various molds, the steel used for molds, according to the working conditions of the molds manufactured by them,
Introduction to Classification of Die Steel
Cold rolled mold steel		Including cold stamping die, wire drawing die, drawing die, stamping die, wire rolling die, wire rolling plate, cold heading die and cold extrusion die. Steel for cold working dies should have high hardness, strength, wear resistance, sufficient toughness, high hardenability, hardening capacity and other technological properties according to the working conditions of the dies manufactured by it.
Hot rolled die steel		It can be divided into hammer forging, die forging, extrusion and die casting, including hot forging die, press forging die, stamping die, hot extrusion die and metal die casting die. The hot deformation die not only has to bear huge mechanical stress, but also has to bear repeated heating and cooling, which causes great thermal stress. Hot-working die steel should not only have high hardness, strength, red hardness, wear resistance and toughness, but also have good high-temperature strength, thermal fatigue stability, thermal conductivity and corrosion resistance, and also require high hardenability to ensure consistent mechanical properties of the whole section.
Plastic die steel		Include thermoplastic molds and thermoset molds. Steel for plastic molds requires certain properties such as strength, hardness, wear resistance, thermal stability and corrosion resistance. In addition, it also requires good manufacturability, such as small heat treatment deformation, good processability, good corrosion resistance, good grinding and polishing performance, good repair welding performance, high roughness, good thermal conductivity and stable size and shape under working conditions. In general, hot-working die steel can be used for injection molding or extrusion molding; Cold-working die steel can be used for thermosetting forming and dies requiring high wear resistance and high strength.
Use of die steel
Cold working die steel		Cold-working die steel is mainly used to manufacture dies for pressing and forming cold workpieces. Such as: cold stamping die, cold stamping die, cold drawing die, stamping die, cold extrusion die, thread pressing die and powder pressing die. Cold-working die steel covers a wide range, ranging from various carbon tool steels, alloy tool steels and high-speed tool steels to powder high-speed tool steels and powder high-alloy die steels.
Hot working die steel		Hot-working die steel is mainly used to manufacture dies for pressure processing of workpieces at high temperature. Such as hot forging die, hot extrusion die, die casting die, hot upsetting die, etc. Commonly used hot working die steels are: alloy die steels with medium and high carbon content and alloying elements such as Cr, W, Mo and V; Hot-working die steel with special requirements is sometimes made of high-alloy austenitic heat-resistant die steel.
Plastic die steel		Because there are many kinds of plastics, the requirements for plastic products are also very different, and different performance requirements are also put forward for the materials used to make plastic molds. Therefore, many industrialized countries have formed a wide range of steel series for plastic molds. Include carbon structural steel, carburized plastic mold steel, pre-hardened plastic mold steel, age-hardening plastic mold steel, corrosion-resistant plastic mold steel, free-cutting plastic mold steel, integral hardened plastic mold steel, maraging steel and plastic mold steel for mirror polishing.
Non-magnetic die steel		Non-magnetic die steel is a kind of high manganese vanadium die steel, which can keep stable austenite in various States, has very low magnetic permeability, high hardness and strength, good wear resistance, and has good comprehensive properties after high proper solution and aging treatment. Good plasticity, high toughness, high work hardening tendency, large thermal expansion coefficient, high resistivity, low thermal conductivity and low magnetism. It is widely used in non-magnetic buildings, non-magnetic machinery, mineral processing and prospecting equipment and military affairs.
