Product Detail
  • Quick Details 

    1: DIN 1.2085 steel introduction
        1.2085 Steel displays the best corrosion resistance in hardened condition with a surface polished to give a mirror finisih. Properties: Magnetizable steelm good mechanical resistance and toughness, excellent for manufacturing of components that have to resist to aggressive plastics, good tool machinability thanks to its sulphur content, suitable for working in wet atmosphere and moisture, suitable for polishing, wear and corrosion proof, and very stable dimensionally during heat treatment.

    4: DIN 1.2085 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 1.2085 is applicable for all kinds of cutting tools - dies and die-blocks in the plastics industry such as PVC, knives, shears, surgical instruments, moulds for plastics production, as well as for surgical instruments and measuring gauges.plates for corrosion resistant mould bases and die sets; moulds for corrosive plastics; the expense for protection and care of mould tools is reduced thanks to increased corrosion resistance; not suitable for mould inserts.

    6:HEAT TREATMENT:
        Usually no heat treatment is required
    Soft annealing: 
        850 to 880 °C for about 2 to 5 hours 
        slow controlled cooling, further cooling in air, annealing hardness max. 240 HB
    Hardening: 
        1000 to 1030 °C 
        keeping curing temperature for 30 minutes 
        quenching in oil is preferable 
        obtainable hardness: 48 HRC
    Tempering: 
       slow heating to tempering temperature immediately after hardening; 
       minimum time in furnace: 2 hour per 20 mm part thickness; 
       tempering twice is recommended



    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.
