Product Introduction
Commonly used rail steels include heavy rail steel specified in GB2585, crane rail steel specified in GB3426, light rail steel specified in GB11264, etc. Heavy rails are divided into 38-43-45-50-60kgheavy rails according to their weight per m (meter) length.
Heavy rails are mainly used for railway trunk lines and need to withstand the pressure, impact load and friction of railway locomotives and vehicles, so heavy rails are required to have sufficient strength, hardness and certain toughness. Heavy rail steel is mainly high-quality carbon steel and high-quality low-alloy steel (such as U71Mn).
