  • Quick Details

    1: DIN 1.2316 steel introduction
        1.2316 is a chrome-molybdenum steel with improved corrosion resistance properties, 1.2316 possesses good polishability, toughness, heat resistance and wear-resistant properties. It is often used for tools for processing chemically aggressive plastic materials (e.g. PVC).
        1.2316 is a martensitic stainless chromium steel with uniform hardness in all dimensions, it is easy to machine, high surface finish and polishability. 1.2316 is commonly used for plastic moulds, and offers a higher corrosion resistance than 1.2083. It can be used with for the manufacturing of chemically aggressive materials like PVC and plastics containing abrasive fillers.

        This grade is not suitable for nitriding and chrome plating because of the high chrome content.
