DC53 - SKD11 Modefied,  High Performance cold work tool steel plates, sheets

 

DC53, is an improvement over the alloy tool steel SKD11 specified in Japanese Industrial Standard (JIS) G4404.

It eliminates the disadvantage of insufficient hardness and toughness, resulting from high-temperature tempering found

with SKD11, and is intended to replace SKD11 in use for general purposes and precision dies.

 

DC53 is a general purpose cold work tool steel with exceptional Toughness, Wear Resistance, Compressive Strength

and Temper Resistance. These properties are obtained through its chemistry as well as its unique manufacturing processes

of ladle refinement, vacuum degassing and forging methods. DC53 also has excellent machining characteristics and is

well suited as a sub-straight for PVD surface treatments.

DC53 can also be hot process CVD and TD (Thermal Diffusion) coated however post heat treat is generally recommended.

Higher hardness after heat treatment than SKD11 - AISI D2 - W.-Nr. 1.2379

A Hardness of HRC 62-63 is secured after tempering at high temperatures (520-530°c).

Therefore, DC53 exceeds SKD11 in strength and wear resistance.

 

Double the toughness of SKD11

DC53 has relatively well-performing toughness among all cold die steels.

Therefore, tools and dies made of DC53 are less faced with the problems such as cracking and chipping, which often

seriously affect conventional tools and dies, and enjoy greater durability.

 

Less residual stress after wire electro-discharge machining

Residual stress is lessened by means of high-temperature tempering. Therefore, problems such as cracking and distortion

are prevented during and after wire electro-discharge machining.

 

Excellent machinability and grindability

DC53 is superior to SKD11 in machinability and grindability. Therefore, the use of DC53 is expected to provide relatively longer

tool life and reduces the number of processes in die making.
