The manufacturer of High Chrome White Iron Grinding Disk tells you that high chromium cast iron refers to white cast iron with a mass fraction of chromium greater than 12%, and it is one of the most widely used wear-resistant cast irons.

There are three types of carbides in high chromium cast iron (Fe, Cr) 23C6, (Fe, Cr) 7C9, (Fe, Cr) 5C, usually abbreviated as M23C6, M7C3 and M3C. M23C6 carbides are easy to appear when high carbon and low chromium are present, M7C3 carbides are easy to appear when low carbon and high chromium are present, and M7C5 carbides can be obtained when carbon and chromium are properly matched. The manufacturer of High Chrome White Iron Grinding Disk tells you that the toughness of high chromium white cast iron is better than that of low chromium white cast iron. At the same time, if the matrix is annealed into pearlite, it can also be machined.
The manufacturer of High Chrome White Iron Grinding Disk tells you that the as-cast structure of high chromium cast iron may be pearlite, martensite, austenite, and the matrix structure of high chromium cast iron is often a mixture of these structures. KNM60 high chromium cast iron has high chromium content, good hardness, corrosion resistance and oxidation resistance, and has higher toughness than ordinary white cast iron, so it is widely used in various abrasive wear occasions and corrosion wear conditions .
