Properties of KH / Abrasion resistance
KH exhibits superior abrasion resistance against slurry wear and sliding wear. In addition, the abrasion between KH materials (measured by the Okoshi method abrasion test) is also suppressed with self-lubrication properties.

Shot blast abrasion test
KH has good properties in terms of powder abrasion. It displays high performance even under high temperature.
