Rail steel is made from pig iron, which is a combination of iron, carbon and other elements. Pig iron is heated and combined with additional ingredients including chromium, nickel, manganese and other metals, to create different grades or varieties of steel. The process of creating steel in this way is called steelmaking.
Rail steel refers to specific varieties of steel used to make railway tracks. It is usually used in track formations and long strings of connected railway tracks. The rail is made up of the rail head and a web section. The rail head is used to provide the flange face or support surface for the wheel, while the web section is designed to provide the mechanical strength and stiffness of the rail.
Rail steel has specific performance requirements for safety and for working with the track. The steel must be resistant to cracking, wear, corrosion and vibration. The steel must also be able to work with the track under high g-forces and maintain strength throughout the length of the track.
The various components of the rail steel must be tested according to the latest standards and specifications of the railway industry. The components are tested for their fatigue, tensile, yield and shear strength and for their wear and impact resistance. The rail steel must also pass a test to prove their ability to be welded together, as well as a special test called wear life testing. It is important that any changes that are made to the rail specifications must be tested to ensure safety and performance.
Rail steel is also used in many high speed trains which must meet strict standards and regulations. They must be made from certain grades of steel and must have high tensile strength. The steel must also be able to resist shock and vibration during travel.
Rail steel is used in many of the worlds rail projects, and is becoming increasingly popular due to its affordability and performance. With the growing demand for rail steel and its many uses, the production and innovation of rail steel is always evolving.
Rail steel is a safe and reliable material that is used to make the tracks that keep people and products moving around the world. It is an essential component of the infrastructure that enables safe transport and a strong global economy.
