Description
Character
1.2316 is a chrome-molybdenum steel with improved corrosion resistance properties, 1.2316 possesses good polish ability, toughness, heat resistance and wear-resistant properties. It is often used for tools for processing chemically aggressive plastic materials.
The mechanical properties are also improved due to the inclusion of molybdenum to the DIN 1.2316 Chemical Composition. The other elements included in its chemistry include nickel, manganese, and silicon. Because the content of chromium is high in the alloy, the material is tough. A high degree of toughness prevents the DIN 1.2316 Plates from getting abraded via any external forces. It is because of this reason that the alloy may be used for tooling purposes. Although specifically, the DIN 1.2316 Plastic Mold Steel Plate makes itself useful as tool steel that is ideal for the processing of plastic materials for example - PVC. PVC is a plastic grade that is known to be chemically aggressive.
