What steel are the wheels of the train made of?
Train wheels are made of killed steel smelted in open hearth furnace, electric furnace or converter.

The chemical composition is generally 0.55-0.65 carbon content. The code name of the wheel steel used by Masteel is CL60, which means that the carbon content is about 0.6%, and there are a few other elements such as silicon and manganese. Generally speaking, wheel steel is high carbon steel.

If the low carbon content leads to insufficient hardness, the train wheels will wear quickly.
