Hard material KH

Basic properties of KH

KH is a material that possesses superior corrosion and wear resistance and high-temperature properties. KH performs well in all environments, including those prone to abrasion, corrosion, and high temperatures.

  1. Exceptional abrasion resistance
  2. Exceptional corrosion resistance
  3. Exceptional high temperature strength
  4. Coefficient of thermal expansion close to that of steel
  5. Diffusion bonding can bond KH to steel
  6. Specific gravity is close in lightness to steel
    (approximately 1/2 that of cemented carbide)

Basic properties of KH

KH is an intermediate material between ceramics and specialty steel. In addition to our stainless-based V, C, and H series, we have introduced an N series, a new nickel-based product lineup. These products have a wide variety of uses in tools and parts requiring abrasion resistance.

  V, C, and H series N series
Hard phase Mo2FeB2 Mo2NiB2
Binder phase Fe-base alloy (stainless steel) Ni-based alloy

KH types and uses

The V, C, H, and N series are prepared with a material of differing hardnesses and strengths (deflective strength). Select the material best suited to your usage environment.
