Cause analysis of manganese stiffness in rail
In the manufacture of rail, in addition to adding more manganese, in the upper rail, the layer and is contacted with a wheel, but also added another kind of metal, indium, it added to the rail on the part of the hardness of the case, even has some toughness, the train wheel is very important it is time, and the "tire" contact, collision, there will be some flexibility, to ensure the safe operation of the train.
If the addition of manganese 13% is made into high manganese steel, it becomes hard and tough. So people use manganese steel to make wear-resistant machine parts and rails, bridges and so on. Manganese steel is mainly used to withstand impact, extrusion, material wear and other harsh working conditions, the form of damage to wear consumption mainly, part of the fracture, deformation.
The characteristics of manganese steel are unique. If the manganese in 2-3% is added to the steel, the low manganese steel is as brittle as glass and cracked at the same time.
