KMX3

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
  • Coining dies
  • Thread-rolling dies
  • Cold-forming rolls
  • Slitter knives
 　

Tenacity Wear-resistance
Higher tenacity than the SKH51 by approximately 20%, even in the hardest range, ensuring a very long life.
 　 Offers wear-resistance equivalent to the SKH51.

Tensile strength Physical characteristics
Offers tensile strength superior to the SKH51.
