DC53 is a general purpose cold work die and mold steel whose strength and toughness approach those of high speed steels.
DC53 is a general purpose cold work die and mold steel whose strength and toughness approach those of high speed steels.

UNIQUE CHARACTERISTICS


  • Higher hardness (62-63 HRc) than D2 after heat treatment.
  • Twice the toughness of D2 with superior wear resistance.
  • 20% higher fatigue strength than D2.
  • Smaller primary carbides than D2 protect the die from chipping and cracking.
  • Secondary refining process (DLF) reduces impurities.
  • Machines and grinds up to 40% faster than D2.
  • Less residual stress after wire EDMing.

    APPLICATIONS

    • Plastic Molds
    • Stepped punch and press-punching dies
    • Concrete sprayer parts, rotor plates
    • Swaging dies and backers
    • Dies for cold forging
    • Thread-rolling circular dies
    • Piercing punch
    • Thread-rolling dies for heat-treated bolts
    • Forming dies
    • Stripper plates for lead frame blanking
    • Gauges
    • Screws for injection molding machines

    BENEFITS

    Welding
    Lower minimum pre- and post-heating temperature than D2 reduces the incidence of weld cracking and simplifies welding. Low hardness decline in heat affected zone minimizes deterioration in die performance.

    Machining/Grinding
    Machines and grinds better and faster than D2 for longer tool life and reduced tool manufacturing time.

    EDM
    Residual stress caused by quenching is minimal in DC53. Therefore, problems such as cracking and distortion are prevented during and after wire electro-discharge machining.
