Mold Steel
Medium plate mold steel is a high-end specialty steel designed for the manufacture of large or precision molds. It determines the forming accuracy and service life of molds, serving as a core material indispensable to modern industries such as automotive and home appliances. Medium plate mold steel is an important indicator of a country's manufacturing capability. As China's manufacturing sector transitions toward high-end and intelligent production, the demand for high-performance mold steel will continue to grow, with domestic substitution and technological innovation set to define the industry's future.
Product Advantages
-
High Hardness and Wear Resistance
Ensures the mold surface resists wear during prolonged, high-frequency stamping or friction, maintaining precision. For example, our developed medium plate mold steel achieves hardness uniformity, tensile strength, and wear resistance that meet high-end industry standards.
-
Excellent Dimensional Stability
Through pre-hardening treatment, the steel is delivered with a specified hardness (e.g., P20 pre-hardened steel at approximately 29-33 HRC), eliminating the need for further heat treatment and preventing deformation during machining and service.
-
Superior Machinability and Polishability
Premium mold steel facilitates cutting and EDM processing, and can be polished to a high mirror finish to meet the surface requirements of precision molds.
-
Reliable Corrosion Resistance
Certain grades (e.g., 1.2311) incorporate chromium, molybdenum, and other elements to enhance resistance to moisture, corrosive gases, or chemical attack, extending mold service life.
Market Applications
