What steel is the rail?

Rails are rail steel. Rail steel is a kind of professional steel, which is used to manufacture tracks such as locomotives and cranes. Rails are divided into railway rails, light rails, conductive rails and crane rails according to Chinese national standards and standards of Ministry of Metallurgy.

China Railway has formed a situation of high density, large axle load and high speed. The synchronous improvement of speed and axle load undoubtedly puts forward higher requirements for the performance of rail. People pay more and more attention to the quality of rail steel.

For the production of rail steel, we should not only ensure its high enough strength, but also improve its toughness. Therefore, we should not simply increase the carbon content, but adopt the way of alloying, that is, develop high-strength and high-toughness rail steel with multi-element carbon alloying. Rail quenching is an effective way to improve the strength, toughness and wear resistance of rail and prolong its service life.
