ASTM A532, or high chrome white iron, has superior abrasion resistance. It is particularly effective in machinery or equipment that experiences grinding, gouging abrasion or crushing. It can significantly reduce downtime and outlasts AR plate and CCO ( by as much as 20 times in the case of CCO) in abrasion resistant applications.

An austenitizing heat treatment usually comprised heating at temperatures between 750 and 790°C (1380 and 1450°F) with a soak time of 8 h. Air or furnace cooling, not over 30°C/h, was conducted followed by a tempering/stress-relief heat treatment. Refrigeration heat treatment is the more commonly practiced remedy for low hardness today.

1. Austenite in high-chromium cast irons is stable up to 500°. At higher temperatures the austenite begins to decompose, causing changes in the hardness, wear resistance, and mechanical properties. 2. The resistance of high-chromium cast iron to hydroabrasive wear is minimal in the cast condition and in the annealed condition. 3.
