Wholesale CSS27P35 Pre-hardened plastic mold steel mold steel mold steel factory price

 CSS27P35 of vacuum melting of chromium - nickel - molybdenum alloy steel, hardened and tempered factory processing, have the following advantages: no risk of deformation and heat treatment quenching crack; without heat treatment costs; shorten the molding cycle; reduce tooling required costs (example, without being deformed Overseas); die easily amended; may be subjected to nitriding and surface hardening treatment to improve the surface hardness and wear resistance of the mold. Alloy tool steel surface decarburization if severe, after machining, with residual carbon layer, so that the final heat treatment in the mold, the inner and outer layers of different tissue and cause significant stress, which leads to quenching cracks mold; other after quenching, the hardness of the surface layer of the mold is low, and the uniform cross-sectional hardness distribution, reducing the life of the mold. Features: None quench cracking and heat distortion risk; without heat treatment costs; shorten the molding cycle; mold easily amended; may be subjected to nitriding and eyes of fire hardened to enhance the mold surface hardness and wear resistance. Pre-hardened, with excellent polishing resistance, processability and electrical resistance. Usage: automobile bumper mold, office equipment, cabinets, appliances plate. Radiator grille.
