440C steel is a high carbon, high chromium martensitic stainless steel known for its high hardness, wear resistance, and corrosion resistance. It is widely used in fields such as cutting tools, bearings, and medical devices.

440C steel is a high carbon and high chromium martensitic stainless steel with high hardness, strong wear resistance, and moderate rust resistance, which is superior to traditional tool steel. 440C steel has strong adjustability in heat treatment, suitable for multiple scenarios such as cutting tools, bearings, and medical devices, with outstanding cost-effectiveness. 440C steel is a classic practical steel in both industrial and civilian fields.

9Cr18Mo steel, as a high carbon and high chromium martensitic stainless steel, has shown significant value in multiple industrial fields due to its excellent hardness and corrosion resistance, especially in providing the wear resistance required for high-precision cutting tools in tool manufacturing. The addition of molybdenum significantly enhances the corrosion resistance of the material, ensuring its stability in harsh environments. The 9Cr18Mo steel grade can achieve a balance of strength and toughness through optimized heat treatment processes, and is widely used in core components such as bearings, precision molds, and chemical equipment.
