Wear and Abrasion Resistance

As a highly wear-resistant material , in the iron-based there is a carbon steel and alloy steel .
In a more highly wear-resistant material there is a ceramic or cemented carbide .
Please choose the material considering the balance of wear resistance and impact resistance.

Wear and abrasion resistance and Shock resistance

"Shock Resistance" and "Wear and Abrasion Resistance"

※Of stainless steel SUS440C is has excellent wear resistance , but is an expensive material.
Please try a low value material KWS4MA with excellent sliding properties in SUS440C equivalent hardness .
The above graph shows the impact resistance and abrasion resistance of the image.
