What is wear resistant steel

Wear resistant steel as a special steel began about the second half of nineteenth Century. In 1883 the British Hadfield (R0.A0.Hadfield) first made of high manganese steel patent, has been 100 years of history, is a kind of high manganese steel wear-resistant steel carbon and manganese content is higher, it has a history of 100 years old steel, because of its use in high impact abrasive wear conditions with strong work hardening ability at the same time, with good toughness and plasticity, and the production process is easy to grasp the advantages, therefore, it is still the amount of wear resistant steel one most (especially in the mining sector). In recent decades, the development and application in the development of low alloy wear-resistant steel is very fast, because of good abrasion resistance and toughness of the steel, the production process is simple, economical and reasonable, applicable in many conditions, users are welcome. In order to meet the needs of mine mining machinery and engineering machinery development, the development of high hardness wear-resistant steel plate, from twentieth Century to 70 in the international series has been formed and standardized in 80s. This kind of steel is the foundation for the development of welded steel in high strength low alloy on the up, they generally use rolling directly after quenching and tempering, or the implementation of controlled rolling and controlled cooling process was enhanced, which can save energy, and alloy element content is low, the price is cheap, but high hardness, wear resistance, process performance can be, because of these advantages make this type of wear resistant steel plate is very popular to the users. Some countries such as Japan, Britain, the United States and other countries are producing such wear-resistant steel.
  Wear resistant steel variety, can be divided into high manganese steel, low alloy wear-resistant steel, chromium molybdenum silicon steel, steel corrosion, corrosion resistant steel and special wear-resistant steel. Some common alloy steels such as stainless steel, bearing steel, alloy tool steel and alloy structural steel are also under certain conditions as wear-resistant steel, due to their convenient source, excellent performance, so in the use of wear-resistant steel also occupy a certain proportion.
