Product Introduction & Application
The GB standard high-toughness heavy rail is an important metal material used for railway tracks. It has high strength, hardness and good toughness, and can withstand the pressure, impact load and friction of locomotives and vehicles.
The main types of railway rail steel in my country are U71Mn (G), U75V (G), U78CrV, etc. For example, the strength grade of U71Mn is 880 MPa, and the strength grade of U75V is 980 MPa. Different steel grades have different mechanical properties to meet different railway transportation needs. High toughness is one of its important characteristics, which enables the rail to avoid brittle fracture when it is subjected to huge loads and impacts of trains, ensuring the safe operation of railways. At the same time, heavy rails also have high strength and hardness to resist wheel wear and extrusion, extending the service life of the rails.

Product Packaging and Shipping
During the transportation of heavy rails, we will use steel belts or steel wires to tie and fix the heavy rails. Heavy rails are usually bundled in a certain number (such as 5-10) and tied with high-strength steel belts. The bundling position is usually at the ends and the middle of the heavy rails, and a bundle is made at a certain distance to ensure that the heavy rails will not loosen during transportation.
The ends of the heavy rails are easily hit and worn during transportation, so special end protectors are used for protection. In order to prevent the surface of the heavy rails from rusting and corrosion, a layer of anti-rust oil or anti-rust paint will be applied to its surface.
Product Application
Common uses:
High-speed passenger railways: U75VG rails are often used for high-speed passenger railways with a speed of 200-250km/h or more. The rails are required to have high dimensional accuracy, high straightness, high surface quality, high strength and toughness, and fatigue resistance to ensure the safe and smooth operation of high-speed trains.
Heavy-duty railways: Heavy-duty railway branches are mainly laid with rails made of materials such as U75V, U77MnCr, and U78CrV with a pressure of 980 MPa or 1080 MPa.
