The manufacturer of High Chrome White Cast Iron Damp Covers tells you that high chromium cast iron is the third generation of wear-resistant material developed after ordinary white cast iron and nickel hard cast iron. Due to the characteristics of the structure of high chromium cast iron, high chromium cast iron has much higher toughness, high temperature strength, heat resistance and wear resistance than ordinary cast iron. High chromium cast iron has been hailed as the most excellent anti-abrasive wear material in contemporary times, and it has been widely used day by day.

The manufacturer of High Chrome White Cast Iron Damp Covers tells you that the good wear resistance of high chromium cast iron mainly depends on its matrix structure and the type and distribution characteristics of carbides.
High chromium cast iron is a multi-element alloy with Fe, Cr, and C as the basic components. The matrix of the freshly solidified high chromium cast iron is austenite, which is stable when heated to a higher temperature, and is saturated with elements such as C and Cr. Manufacturers of High Chrome White Cast Iron Damp Covers tell you that 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-chromium cast iron is a chromium-based white cast iron with a chromium content between 12% and 28%. Due to the addition of a large amount of chromium, the M3C carbide in the white iron becomes M7C3 carbide. This alloy carbide is very hard and gives high chromium cast iron good wear resistance. The manufacturer of High Chrome White Cast Iron Damp Covers tells you that on the other hand, during the solidification process, M7C3 carbides are distributed in rod-shaped isolation, which improves the toughness of high chromium cast iron to a certain extent.
