Tool steel
KMX3S70 High-Speed steel
The KMX3 is high-wear-resistance, high-tenacity, and high-cost-performance high- speed tool steel for cold plastic machining that features hardness as high as 64 HRC or more.
　
Features of KMX3

1.Superior cost-performance　●* Superior performance equivalent to the SKH51 offers high cost-performance.
2.Superior tenacity 　●Greater tenacity than the SKH51 suppresses cracks and chipping, which are the causes of a shorter service life of tools.
3.Safe tool life 　●Hardness as high as 64 HRC or more, and wear resistance equivalent to the SKH51 ensures wide applications to tools.
　
Applications Position of KMX3
●Cold punching
●Trimming dies
