New Generation of Cold Work Die Steel created by Nippon Koshuha.

Improved service life of die	Improved die manufacturing efficiency

Outstanding surface treatment characteristics
Designed to get hardness to 62HRC by heat treatment, which guratantees that the surface coating is hard to peel off against high load pressure, leads to longer service life of die

Exceptional toughness
Improves toughness twice and higher than that of SKD11, which extends the service life of die by solving the problem caused by cracking.

Excellent dimensional change characteristics by heat treatment
Around 50% lower in dimentional change and directional variation than SKD11 and reduces the number of finishing process.
