With the rapid economic development, die steel is widely used in the manufacturing industry. A large number of mould steels are used in the manufacture of dies and moulds for manufacturing various products. Die steel Characteristics:
1. High hardness
The hardness of die steel is generally between HRC50 and HRC60, which is more than twice that of 45 steel. Therefore, in a certain range of temperature, the hardness of die steel is better than that of other steels, so as to ensure its wear resistance, toughness and strength.
2. Good red-hardness
The red-hardness of die steel is very high, which ensures that die steel will not become brittle at high temperature. This can be used to ensure the accuracy and strength of dies and moulds in the process of continuous punching, extrusion and other processing.
3. Strong impact resistance
High hardness and strong internal structure of die steel make it have strong impact resistance, which enables it to process various shapes with higher precision and strength when impacting and forming.
4. High quenching stability
Die steel has good quenching stability, which can effectively prevent deformation or cracking during the quenching process, and has good performance after quenching and tempering.
5. Good machinability
Die steel can be trained for cutting and cutting without damaging the surface, and has high rigidity and accuracy.
In summary, die steel has excellent hardness and impact resistance, good red-hardness and quenching stability, and high machinability. All of these characteristics make die steel an ideal material for manufacturing dies and moulds.
