    DC53 die steel

    DC53 is SKD11 the new improved cold die steel, its technical specifications set out in the Japanese Industrial Standard (JIS) G4404. It overcomes the hardness and toughness of high-temperature tempering SKD11 lack of weaknesses in the general field of precision molds and replace the SKD11.
    DC53 heat treatment hardness is higher than SKD11, high temperature (520-530 ℃) after tempering up to 62-63HRC hardness, strength and wear resistance in the DC53 over SKD11.
    SKD11 toughness is 2 times, DC53 die steel toughness in the cold is more prominent, with the DC53 made little cracks and cracking tools, greatly improving the service life.
    Line cutting the smaller the residual stress after annealing at high temperature to reduce the residual stress after wire cutting cracks and deformation to be curtailed.
    Cutting and abrasive than SKD11, DC53 cutting and abrasive than SKD11, use the DC53 tools can increase tool life and reduce the manufacturing processes.
    Uses:
    Precision stamping die
    Precision wire cutting and a variety of purposes Die Stamping Die
    Plastic deformation of materials difficult to machine tools
    Cold forging, deep drawing and Roll with the model
    Other
    High-speed blanking punch, stainless steel punch
    Factory state: HB255
    Practical features:
    (1) is cutting, grinding was good.
    By cutting, abrasive are better than SKD11 was excellent, so the processing tool life longer processing time than the number of provinces.
    (2) heat treatment on the merits
    Higher than the SKD11 hardened, it can improve the hardness of the vacuum heat treatment, lack of defects.
    (3) the advantages of on-line cutting
    Reduce the residual stress by heat tempering and elimination of residual austenite, to prevent the wire cutting cracks, deformation of the problems.
    (4) the advantages of surface hardening treatment
    Surface hardness of the surface hardening treatment than SKD11 high, mold can improve performance.
    (5) repair welding operations on the merits
    As the warm and hot temperatures than SKD11 after low, so relatively easy to repair welding operations.
    Nitriding:
    Workpiece obtained by nitriding the surface hardened layer of dense tissue, so that the wear resistance and corrosion resistance workpiece significantly increased. 525 ℃ after gas nitriding surface hardness of about 1250HV, 570 ℃ soft-nitriding surface hardness of about 950HV.
    Density
    DC53 die steel slightly heavier than the average density of 7.9g/cm 3
