Abrasion (mechanical) - Wikipedia

Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index). The former is the amount of mass lost per 1000 cycles of abrasion. The latter is the ratio of former with the known abrasion rate for some specific reference material.

Taber Abraser - (Wear & Abrasion) - Taber Industries

Taber Wear Index - Indicates rate of wear, and is calculated by measuring the loss in weight (in milligrams) per thousand cycles of abrasion. The lower the wear index, the better the abrasion resistance. I = [(A - B) * 1000] / C where I = wear index. A = weight (mass) of specimen before abrasion. B = weight (mass) of specimen after abrasion

The corrosion resistance of this type of steel is due to a very thin, not visible oxidic protective film which is formed when the chrome content is >12 %. The corrosion resistance increases with the chrome content. However, if the chrome content is more than 20 %, the steel loses its hardenability and thus its wear resistance.
