PCR mold steel is suitable for making plastic forming molds containing fluorine and chlorine and has good corrosion resistance. Specific applications, such as fluoroplastic or polyvinyl chloride plastic forming molds, fluoroplastic microwave panels, plastic doors and windows, various vehicle handle covers, fluorochloroplastic extruder screws, barrels and plastic forming molds with flame retardants, it can be used as a substitute material for 74PH steel.
Polytrifluoroethylene valve cover mold, originally made of 45 steel or chrome-plated, with a service life of 1000-4000 pieces, using PCR mold steel, after processing 6000 pieces, it is still the same as the new mold, no rust or wear is found, and the mold life is up to 10,000 -12000 pieces. PTFE plastic microwave plate, the original use of 45 steel or surface chrome-plated mold, the service life is only 2-3 times, the use of PCR mold steel, after the mold has been used for 300 times, no rust or wear was found, and the surface was as bright as a mirror.
