Which steel is used in steel rails?

Oct 30, 2025 Leave a message

Hot rolled steel is the basic material used to make railway rails. The great strength of hot rolled steel ensures that the rails can support the weight of trains and survive deformation over time. The rolling process provides the steel a surface polish that improves grip between the track and the train's wheels, resulting in greater stability and safety.
