High-chromium cast iron is an abbreviation for high-chromium white-port wear-resistant cast iron. It is a kind of anti-wear material with excellent performance and special attention. It is much higher wear resistance than alloy steel, and much higher toughness and strength than normal white cast iron. At the same time, it also has good high temperature resistance and corrosion resistance, combined with convenient production and moderate cost. It is regarded as one of the best anti-abrasive wear materials in the world. It is widely used in mining, cement, electric power, road machinery, and refractory materials. It is commonly used in liners, hammerheads, plate hammers, and grinding balls.
The metallographic structure of the higher-quality and high-chromium cast steel is: tempered martensite + eutectic carbide + retained austenite + secondary carbide. Its impact toughness is higher than that of high chromium cast iron, and the remaining mechanical properties are comparable. High cost-effective "new medium carbon chromium alloy steel wear liner", its performance is superior to the traditional medium carbon chromium alloy steel liner, high toughness, good wear resistance, low product cost, cost-effectiveness has a certain advantage longer life Jinyangshi's new micro-alloy material is more wear-resistant than traditional materials and has been widely recognized. Widely used in mining, building materials, thermal power and other mechanical equipment, production of wear parts.
