  • The uneven hardness of die steel after heat treatment will reduce the wear resistance of the die and affect the service life of the die. The reasons for these phenomena are as follows: 1. The steel with low hardenability is selected for the large die. 2. The original carbide segregation is serious in the steel die. 3. The die forging process is not correct, and the spheroidizing structure is not good after forging. 4. There is annealing decarburization layer on the surface of the die or the decarburization layer is produced during quenching and heating.

  • NAK80 is a pre hardened plastic die steel. The factory hardness can reach hrc37-43. Good machinability and polishing performance. Used in mirror polishing mold, automobile parts EDM mold, thickness not more than 2 mm thin plate, high efficiency blanking die, blanking die and stamping die, various scissors, inlaid blade, woodworking blade, thread rolling die and wear-resistant slider, cold upsetting mold, thermosetting resin forming mold, deep drawing mold

  • Generally, the selection of steel grades can be divided into the following four situations: (1) cold working dies with small size, simple shape and light load. For example, small punch, scissors for cutting steel plate can be made of t7a, T8A, T10A, T12A and other carbon tool steels. This kind of steel has the advantages of good machinability, low price and easy source. But its disadvantages are: low hardenability, poor wear resistance, quenching deformation. therefore

  • H13 steel is a kind of c-cr-mo-si-v steel, which is widely used in the world. At the same time, many scholars in various countries have carried out extensive research on it and are exploring the improvement of chemical composition. Steel is widely used and has excellent properties, which is mainly determined by the chemical composition of steel. Of course, when the content of sulfur in the material is reduced from 1550.005% to 1550.005%, the toughness of steel must be reduced from 1550.005%
