GB Standard Is Used For Rail Carbon Steel Rail Price Concessions

Short Description:

Steel rail is an important part of the track structure. It is responsible for guiding the wheels and transmitting loads. It needs to have sufficient strength, stability and wear resistance. The section shape of the rail is I-shaped, so that the rail has the best bending resistance. The rail is composed of a rail head, a rail waist and a rail bottom.

    GB steel rail have been an integral part of transportation systems worldwide, providing a convenient and efficient means of commute and cargo transportation. At the heart of this vast network lies a crucial component: train rail steel. These steel tracks, which support the movement of trains, play a vital role in maintaining the safety and longevity of the railway system. In this blog, we will explore the significance of train rail steel and its importance in the production of durable and reliable railway tracks.

    Standard: GB11264-89 GB2585-2007 YB/T5055-93
    Material: U71Mn/50Mn
    Length: 6m-12m 12.5m-25m


    The type and strength of steel rail suppliers  are expressed by the approximate mass (kilograms) per meter of length. For example, the current standard rail types in China are 43kg/m, 50kg/m, 60kg/m, 75kg/m, etc. The standard length of rails in China: 43kg/m is 12.5m or 25m; the length of rails above 50kg/m is 25m, 50m, and 100m. Go to the rail welding factory to weld it into a 500m long rail, and then transport it to the construction site and weld it into the required length.



    Good corrosion resistance: The surface of channel steel can be treated with anti-corrosion to improve its corrosion resistance and extend its service life.

    Wide range of applications: Channel steel can be used in building structures, machinery manufacturing, bridge construction, shipbuilding and other fields, and has a wide range of applications.

    In general, channel steel has the characteristics of high strength, simple manufacturing process, regular shape, good corrosion resistance and wide application. It is a commonly used structural material.



    Methods to improve rail stiffness and wear resistance include:

    Choose high-strength materials: Choosing suitable rail materials, such as alloy steel or high-strength steel with good wear resistance, can improve the rigidity and wear resistance of the rails.

    Optimize the geometry of the rail: By changing the rail's cross-sectional shape, rail waist width, rail squat height and other parameters, the stiffness and wear resistance of the rail can be improved.

    Strengthen the heat treatment of rails: Through appropriate heat treatment processes, such as normalizing, quenching, etc., the strength and hardness of rails can be improved, thereby improving stiffness and wear resistance.

    Improve the surface hardness of the rail: Surface quenching, surface spraying of ceramic coatings and other methods can be used to increase the hardness of the rail surface and improve wear resistance.

    Adding appropriate alloying elements: Adding appropriate alloying elements, such as chromium, titanium, etc., to the material can increase the hardness and wear resistance of the rail.

    Strengthen the maintenance of rails: conduct regular inspection, repair and lubrication to keep the rails in good condition and extend their service life.

    It should be noted that the above methods should be selected and applied according to specific conditions and needs to achieve the purpose of improving rail stiffness and wear resistance.
