Train Rail: Used to laying railway, should bear the pressure of train, impulse load and friction, require sufficient strength and toughness. The quality requirements is stringent, in addition to its chemical composition, the mechanical properties, falling weight test and acid leaching group are also required. The manufacture factory has Wuhan Steel, Anshan Steel, Baotou Steel and Panzhihua Steel.

Crane Rail: The height is low, the size of head width and web thickness is big. Only require to check the chemical composition and tensile strength. Used to laying crane and little car rail. The factory has Anshan Steel and Panzhihua Steel.
