The characteristic steel of the material is high wear-resistant micro-deformation cold work die steel, which is an air-hardened tool steel. The mass fraction of carbon in this steel is as high as
and the mass fraction of chromium is as high as . The hardness can reach up to 100% after heat treatment, but its ductility, toughness, and rust resistance are relatively weak, and the surface of the steel is difficult to mirror polish. deal with. As cold stamping products develop toward high precision, high efficiency, and multiple varieties, mold steel is required to have good wear resistance and toughness.
Compared with steel, the chemical composition of this steel is increased, which changes the casting structure of steel, improves the morphology of ledeburite, has better toughness and wear resistance than steel, and increases the service life of the mold. . Since the yield point and plastic deformation resistance of this steel are higher than those of steel, its forging performance and thermoplastic formability are slightly worse than those of steel.
Although the chemical compositions of domestic steel, American steel and Japanese steel are the same, their properties are very different. After heat treatment, the color of domestic steel is slightly orange-red, and the deformation is generally large. It is prone to accidental fatigue fracture during actual use. The color of steel is cold white, the hardness is higher than steel, and the toughness is not as good as steel. Micro chips are prone to appear in high-stress areas, while steel has a smooth color. Best overall performance.

Typical application examples
Used in the drawing mold for the rear cover of the refrigerator compressor of Kelon Electrical Appliances Division, with a quenching hardness of ~.
In order to improve the service life of cold work die flat steel materials, using the method of Tianguo rare earth, the
wear resistance and impact toughness of the steel are greatly improved, thereby achieving the improvement of die flat steel rolling materials. service life purpose.
Since the content of polyethylene in steel is higher than that of steel, it has better overall performance, and traditional
steel will gradually be replaced.
The rolling wheels and clutch adjustment plate cold punched dies made of steel can extend the service life by
times compared with steel.
