Product Description

Product Description

DC53 Cold Work Tool Steel Flat Bar

DC53 Cold Work Tool Steel 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.

Characteristics

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.


 

Our Advantages

Benefits of DC53 Tool Steel
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 EDM.

 

Applications

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

Typicak Application for DC53 Tool Steel:
-- Forming Dies
-- Thread Rolling Dies
-- Cold Forging Dies
-- Gauge
-- Plastic Molds
-- Steped Punch
-- Press Punching Dies
