Product Detail

  • Quick Details


    1: DIN 1.2083 steel introduction
        1.2083 Steel is typical Stainless Chrome Plastic Mold Steel. German die steel 1.2083 is a chromium content up to 13% of the plastic die steel. 1.2083 mold steel has good polishing and excellent wear resistance, is often used to prevent acid plastic mold. Special Steel China Supplier and factory -OTAI SPECIAL STEEL COMPANY supply 2083 steel in round bar, plate, flat bar, square, block and others any shape.

    4: DIN 1.2083 steel mechanical properties
        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

    Application  DIN 1.2083 is applicable for electric erosion operation, suitable for acid good polishing mold plastics and requirements. Mainly used in the production of PVC mold, wearability and filling the mold, including the hot hard type of plastic mold, long-life mold, such as: disposable tableware mold, optical components production, such as camera, and the sunglasses, medical containers and etc.

    6.Heat Treatment
    Annealing
        Slowly heat to 750-800℃，then slowly Cools to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 225 Max
    Hardening
        1.2083 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested.
    Quenching 
        Quenching temperature / ℃ : 1020~1050
        Quenching medium: Oil cooling
        Hardness: 50 HRc
    Tempering 
        Tempering temperature / ℃ : 200-300
        After tempering hardness HRC or higher: 28-34 HRc


    7: Delivery condition
        For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
        For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

        For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
