  • The intention of final heat treatment of die steel is to improve the mechanical properties such as hardness, wear resistance and strength. So how is the final heat treatment?

    1. Quenching includes surface quenching and whole quenching. External quenching is widely used because of less deformation, oxidation and decarburization, and has the advantages of high external strength, good wear resistance, and excellent internal resistance and impact resistance.

  • The preparation for heat treatment of die steel is primarily to improve processing performance, eliminate internal stress and prepare excellent metallographic structure for heat treatment after all.

    1. Annealing and normalizing annealing and normalizing are used for hot worked blanks. In order to reduce the hardness of carbon steel and alloy steel with carbon content more than 0.5%, annealing treatment is often used; for carbon steel and alloy steel with carbon content less than 0.5%, normalizing treatment is used to prevent tool sticking when cutting with low hardness.

  •   D2 cold working die steel D2 is a widely used high carbon and high chromium cold working die steel, which has high wear resistance, hardenability, hardenability, micro deformation, high thermal stability and high bending strength; D2 can be used to manufacture some cold work die steel with large cross-section, complex shape and high wear resistance, which is suitable for manufacturing high-precision and long-life cold working die, such as complex shape punching die and cold extrusion die The machine has the advantages of high precision, high precision and high precision.

  • 1.2738 die steel is pre hardened plastic die steel, which adopts advanced refining technology of die steel and is Cr Ni Mo alloy steel melted in vacuum. This kind of steel has good polishing, light etching, machinability and wear resistance; large mold does not need heat treatment, because it does not have the risk of quenching crack and heat treatment deformation; the mold must be softened and annealed before quenching and tempered in time after quenching

  • The pre heat treatment of H13 steel and die blank supplied in the market has been well done in the steel plant to ensure good metallographic structure, proper hardness, good workability and no need for annealing. However, the original structure and properties are destroyed and the forging stress is increased after the modification. Therefore, re annealing is necessary

  •   Plastic mould steel The life span is generally divided into five levels. The first level is more than one million times, the second level is 500000-1000000 times, the third level is 300000-500000 times, the fourth level is 100000-300000 times, and the fifth level is less than 100000 times.
