In general, abrasion resistance is roughly proportional to material hardness. However, a number of other features, such as coefficient of friction and how the material treats lubricating materials (water, oil, asphalt, etc.) affect the performance of the material. Fortunately, CRODON excels in all these parameters.

Among highly abrasion resistant materials, the CRODON wear surface is special for its low coefficient of friction (lowest of all metals and below Teflon) and how it treats lubricating fluids. Its low coefficient of friction eliminates sticking. But, more importantly for wear, a low coefficient of friction also limits side wall pressure limiting the actual abrasive force applied to the surfaces of materials subject to wear.

Because the CRODON wear surface is non-reactive to water, oils, and most other liquids, its wear resistance doesn't break down due to non-abrasive forces the way most steel and steel alloys do.

The CRODON wear surface naturally creates a protective "boundary" layer that limits "adhesive wear", the most prevalent wear when water, oil, hot asphalt or other liquids or near liquids are present. No other sever wear plate surface offers this performance characteristic.

The CRODON wear surface is harder than most materials that cause wear. It measures 1000 Knoop (approximately 900 Brinnel or 70 - 72 Rockwell C). In the field CRODON standard plate (with mild steel as the base) has shown a life cycle equal to 4 to 10 times (or more) the life of ½" thick AR400 wear plate and up to 5 times the life cycle of ¼" thick alumina ceramic tile. Bench testing has shown similar results as the field, depending on the material used as abrasive.

No other product on the market offers the combined characteristics to limit abrasion: low coefficient of friction, natural "boundary layer" lubrication, and extreme hardness.
