Chrome steel typically has a hardness of 60 to 64 HRC and a very low impact strength of 10 J/cm². To prevent the breakage of chrome steel blow bars, there may not be any unbreakable elements in the feed material. Chrome steel is the common material in casting HSI blow bars because it has a very good hardness.

The most common abrasion test however, is the Bond method where a 76x25x6mm (3x1x0.25″) piece of 500 Brinell SAE 4325 chrome-nickel-molybdenum steel rotates in a falling stream of rocks under standard predetermined conditions to measure its weight loss. The resulting Ai is used to predict crusher liner wear rates.
