With the development of modern industry, the demand for precision stamping dies is increasing. As an indispensable tool in the manufacturing industry, the performance of stamping dies directly affects the quality and production efficiency of products. Among many materials, cold work tool steel has become an ideal material for precision stamping dies due to its excellent performance.

 

Characteristics of Cold Work Tool Steel

High Hardness and Wear Resistance

After quenching and low-temperature tempering, the hardness of cold work tool steel can usually reach HRC58-64. This enables it to maintain a sharp cutting edge and shape under high stress conditions, thereby extending the service life of the mold. High hardness is the basic characteristic of cold work tool steel, which ensures that the mold will not lose its working ability due to softening of the material during use. Wear resistance ensures that the mold can still maintain its shape and precision after long-term use, and will not affect the product quality due to wear.

Good Toughness and Impact Resistance

While maintaining high hardness, cold work tool steel also has good toughness, which can effectively resist impact and vibration, thereby reducing damage and breakage of the mold. The importance of toughness lies in its ability to absorb impact energy and prevent brittle fracture of the mold under high stress conditions. Good toughness allows cold work tool steel to maintain its structural integrity under complex stress environments and avoid fracture or edge collapse.

High Hardenability

Cold work tool steel can achieve uniform hardness distribution during heat treatment to ensure the overall performance of the mold. After heat treatment, steel with good hardenability can achieve similar hardness on the surface and inside, which is of great help to the service life and performance stability of the mold. High hardenability ensures the core hardness of large-size molds, giving them consistent mechanical properties and improving the overall durability of the mold.

Excellent Fatigue Resistance

Cold work tool steel can maintain stable performance under high-frequency impact and cyclic loads, reducing the possibility of mold fatigue failure. High fatigue resistance means that the mold will not suffer fatigue fracture due to stress concentration during long-term use. Good fatigue resistance makes cold work tool steel suitable for high-load and high-frequency stamping operations, extending the service life of the mold and improving production efficiency.

 

Applications of Cold Work Tool Steel in Stamping Dies

Cold work tool steel is widely used in stamping dies. It can be used for die components like punches, dies, and strippers which need high hardness, wear resistance and toughness to bear repetitive impact and friction during stamping. It is also suitable for blanking and piercing dies to have good cutting performance and durability for accurately cutting through sheet materials. In bending dies, it ensures proper shaping and forming of the workpiece with sufficient strength and stiffness. For deep drawing dies, it helps in achieving smooth and accurate drawing of the workpiece without significant deformation or damage. Progressive dies also benefit from it due to the complex and continuous stamping process. Mold inserts are often made of cold work tool steel to provide specific features or functions within the stamping die. The choice of cold work tool steel depends on factors such as the type of stamping operation, the material being processed, the required die life, and the production volume, as different grades offer varying combinations of hardness, toughness, and wear resistance to meet specific needs.
