DC53 is a new general-purpose cold work die and mold steel whose strength and toughness approach those
of high-speed steels.
DC53, is an improvement over alloy tool steel D-2 specified in Standard (JIS) G4404. It eliminates the disadvantages
of insufficient hardness and toughness, resulting from high-temperature tempering found with D-2, and is intended to replace D-2 in use for general purpose and precision dies.
Higher hardness (62-64 HRc) than D2 after heat treatment.
Twice the toughness of D2 with superior wear resistance.
Substantially higher fatigue strength compared to 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.
It is used for making 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 and plastic molds as well.
