Summarization
High Cr white iron material possess a combination of superior abrasion resistance and a reasonable
degree of toughness. The high Cr castings have longer service life than the other material,such as
high Mn steel and Cr-Mo alloy steel.And now 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 excellent performance.
