Introduction
New Generation of Cold Work Die Steel created by Nippon Koshuha.
Characteristics
| 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. | |
| Superior machinability | |
Improves machinability twice and higher than that of SKD11 and saves time and cost for die making. | |
