The main difference between 55Q and Q235 rail is the carbon content. In addition, the brittle toughness, tensile strength and impact strength of the two materials are different. 55Q rail is mainly used for mine track steel. 55Q rail has higher hardness and better wear resistance than Q235 rail. And the other is the more commonly used model, if there is no special requirement, Q235 material will be used. Finally, there is another reason that the price of Q235 steel rail is lower than that of another kind. railway track material

Rail made of 55Q material has high strength, good wear resistance and stable performance, and is generally used as a track for small locomotives and vehicles in mines, factories, forests and urban traffic. Q235B is made of ordinary carbon structural steel. Its wear resistance and strength are not as high as 55Q. It is usually used in relatively small tracks. railway track material
