- Steel is a highly wear-resistant micro-deformation cold work die steel, which is an air-hardened tool steel. The steel has a mass fraction of carbon up to
- and a mass fraction of chromium up to
-. After heat treatment, the hardness can reach
-, but its ductility, toughness and rust resistance are relatively weak. The surface of steel is also difficult to mirror polish. 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 the steel and improves the morphology of ledeburite. The toughness and wear resistance are better than steel, which increases the service life of the mold. Since the yield point and plastic deformation resistance of this steel are higher than - steel, its forging performance and thermoplastic formability are slightly worse than - steel.
- Domestic
- Steel, United States
- Steel, Japan
- Steel, although the three have the same chemical composition, 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 domestic steel is cold white, and the hardness is higher than
- Steel , toughness is not as good as
steel, small chips are prone to occur at high stress areas
-steel has a smooth color and the best overall performance.

. In order to improve
- the service life of cold work die flat steel materials, using Tianguo rare earth method, the wear resistance and impact toughness of the steel are greatly improved, thereby achieving The purpose of improving
- the service life of mold flat steel rolled products.
. Since the content of
