p20 steel
P20 steel is a versatile pre hardened mold steel that has become an industry standard in plastic injection molding and tooling applications. This low carbon alloy steel typically contains chromium, molybdenum, and manganese, offering an excellent balance of hardness, machinability, and wear resistance. With a hardness range of 28-32 HRC, P20 steel delivers consistent performance across various manufacturing processes. The material's uniform hardness throughout its cross section eliminates the need for additional heat treatment, making it particularly cost effective for large mold applications. P20 steel's superior polishability and ability to accept various surface treatments make it ideal for producing high quality plastic parts with excellent surface finishes. Its good thermal conductivity properties help maintain consistent cooling rates during the molding process, resulting in reduced cycle times and improved part quality. The material's excellent dimensional stability during machining and minimal distortion characteristics ensure precise mold geometries, crucial for maintaining tight tolerances in finished products. Additionally, P20 steel's weldability allows for easy modifications and repairs, extending the service life of molds and reducing maintenance costs.
