High Cr white cast irons have a combination of superior abrasion resistance and a reasonable degree of toughness. At present, it is widely used in the working condition of high wear and low impact such as dry grinding process, coal mills, cement mills due to its longer service life than the other materials, such as high Mn steels and Cr-Mo alloy steels.

     ASTM A 532/A 532M-93a Standard Specification for Abrasion Resistant Cast Irons covers a group of white cast irons that have been alloyed to secure high resistance to abrasive wear in the application of the mining, milling, earth handling, and manufacturing industries, in which the Method of Manufacture, Heat Treatment, Chemical Composition Requirements, Microstructure, Hardness Method and Requirement are introduced in detail. Tables 1 and 2 are chemical composition requirements and hardness requirement.
