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.
※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.
