Product features: Precision can achieve 0.002mm, with a wide range of types available. Non-standard products can be customized according to customer requirements. Depending on the stamping material and thickness, different impact-resistant and wear-resistant materials are used. Both concentricity and working surface tolerances can be controlled within 2um, maintaining a mirror-like finish, enabling customers to utilize the best products in the shortest time.
Product Material: SKH-51 Hardness: 62-64 ° HSS Hardness: 60-62 ° KG7 Hardness: 89-91 °
Characteristics of SKH-51: SKH-51 is an internationally recognized tungsten molybdenum series ductile high-speed steel. The carbide particles of this steel are small and uniform, with high toughness, excellent cutting performance, and good thermoplastic properties. It has good wear resistance, especially can resist high temperatures of 600 ℃ and is not easily softened. It has good red hardness and can reach a hardness of 64HRC after heat treatment quenching. Its wear resistance is twice as high as that of high chromium high carbon steel, and its machinability is 1.5 times stronger. The disadvantage is that the heat treatment process is difficult and the cost of use is high.
