Wear-resistant steel

There are many kinds of wear-resistant steel, which can be roughly divided into high manganese steel, medium and low alloy wear-resistant steel, chrome-molybdenum-silicon-manganese steel, cavitation-resistant steel, wear-resistant steel and special wear-resistant steel. Some general alloy steels such as stainless steel, bearing steel, alloy tool steel and alloy structural steel are also used as wear-resistant steel under specific conditions. Because of their convenient source and excellent performance, they are also used in the use of wear-resistant steel. The linings of many large and medium-sized ball mills in the United States are made of chrome-molybdenum-silicon-manganese or chrome-molybdenum steel. Most of the grinding balls in the United States are made of medium and high carbon chromium molybdenum steel.

wear-resistant steel

Wear-resistant steel is widely used in mining machinery, coal mining and transportation, construction machinery, agricultural machinery, building materials, electrical machinery, railway transportation and other departments. For example, steel balls, lining plates of ball mills, bucket teeth and buckets of excavators, rolling mortar walls, tooth plates and hammer heads of various crushers, track shoes of tractors and tanks, strike plates of fan mills, railway ruts Forks, middle groove-in-plates, grooves, circular chains for scraper conveyors in coal mines, blades and teeth for bulldozers, linings for large electric wheel truck buckets, roller cone bits for perforating oil and opencast iron ore, etc. , the above list is mainly limited to the application of wear-resistant steel that is subjected to abrasive wear, and all kinds of workpieces with relative motion in various machines will produce various types of wear, which will improve the resistance of workpiece materials. Grindability requirements or the use of wear-resistant steel, the examples are numerous. The grinding media (balls, rods and liners) used in ore and cement mills are high consumption steel wear parts.
