Features of High Chrome White Iron Mantle

The good wear resistance of High Chrome White Iron Mantle mainly depends on its matrix structure and the type and distribution of carbides.

High Chrome White Iron Mantle is a multi-component alloy with Fe, Cr and C as the basic components. The matrix in the high-chromium cast iron that has just solidified is austenite, which is stable when heated to a higher temperature, and is saturated by elements such as C and Cr. When the temperature is lowered, the austenite will transform. Under normal conditions, high-chromium cast iron presents a multi-phase structure dominated by austenite. Cast iron with this structure can better exert the potential of the material itself when used at high temperatures.
High Chrome White Iron Mantle is a chromium-based white cast iron with a chromium content between 12% and 28%. Due to the large amount of chromium added, the M3C-type carbide in the white iron becomes M7C3-type carbide. This alloy carbide is very hard and imparts good wear resistance to high chromium cast iron. On the other hand, during the solidification process, the M7C3 carbides are isolated and distributed in rod shape, which improves the toughness of high chromium cast iron to a certain extent.
