Rails are hot rolled from continuously cast blooms or rounds having the appropriate cross-section for the rails to be produced. They can also be rolled from near-net shape continuous cast rails, which saves time, energy, and cost by minimizing the processing needed to get the rail to its final shape.
Steel Rails are the key parts of the rail track laid in two parallel lines to provide a continuous, steady and level surface for the runnings of trains. Heavier train and fast speed requires higher requirements to withstand stresses, so they are produced from high carbon steel (carbon -0.6 % to 0.8 %, manganese 0.8%-1.3 %, silicon 0.1 % -0.5 %, sulphur and phosphorus0.03 % maximum each, and aluminum 0.015 % maximum). Some grades of steel contain chromium (Cr- 0.8 % to 1.2 %). Steel Rails are also produced from special steels containing niobium (Nb- 0.04 % max.) or vanadium (V-0.2 % max.). In fierece conditions steel rails has to be made from corrosion resistant steels have also been developed.
| No. | Element | Function |
| 1 | C | Improve the strength, hardness, and wear resistance of the rail. The carbon content of domestic rails is 0.65% to 0.82%. |
| 2 | Si | It is easy to combine with oxidation, and can play the role of removing bubbles in the metal. The steel contains an appropriate amount of silicon, which can improve the hardness and wear resistance of the steel. |
| 3 | Mn | It is a beneficial element that can improve the strength and wear resistance of steel and increase the toughness of steel. It can remove harmful iron oxide and sulfide inclusions in the steel. |
| 4 | Cu | It is a beneficial element. Steel contains a small number of copper compounds, which can improve the fatigue resistance and corrosion resistance of steel. |
| 5 | P | It is a harmful element. The biggest hazard of phosphide is to reduce the plasticity and toughness of the steel. |
| 6 | S | The sulfur is a harmful element. It is often left in the steel in the form of granules. |
Steel Rail Role in Railtrack System
Steel rail is the most important part in rail track system, it is a steel profile with shape of inverted T. Variety of steel rails are developed with different weight and dimensions. All types of Steel Rail has hardend head and flat bottom. This special shape is designed with a group of rail fastening parts that fix steel rail on rail sleepers: Rail Spike, Screw Spike, Elastic Rail Clip, Rail Clamp, etc.
