Understanding the Hardness of Rail Steel
The manufacturing process plays a crucial role in determining the hardness of rail steel. During the production process, rail steel undergoes several stages, including melting, casting, rolling, and finishing. Each of these stages affects the microstructure of the steel, which in turn affects its hardness.
