The Classification of Steel Rail

Steel Rail is generally divided into three levels according to the tensile strength, that is, the general standard rail (tensile strength of 70 - 85 kgf/mm2), wear-level rail (tensile strength of 90 - 105kgf / mm2) and extra rail (tensile strength 110 - 125kgf / mm2). 

The chemical composition of the steel rail, strength and elongation must meet the standard requirements, in addition to be hammer, metallurgical, low times, check hardness testing and surface quality and dimensional deviations. The world's first rail is manufactured with a carbon content of 0.3 to 0.4% carbon steel. Carbon rail States currently still widely used, but the steel carbon content gradually increase (C0.5 - 0.8%). In some steel manganese content also increased (Mn0.6 - 1.0%). China's heavy rail steel standard component: C0.67 - 0.80%, Si0.13 - 0.28%, Mn0.7 - 1.0%, P≤0.04%, S≤0.05%, with the rolling stock axle load, vehicle speed and increase in traffic in improving rail weight per unit length, developed alloy rails, improve rail production technology and product quality has also continued to make progress.
