Wide size range available and oldest EN 10297-1 Steel Tube Manufacturer, find updated BS EN 10297 Tube Standard price in India.
Solitaire Steel is a trusted exporter and supplier of E355 Steel Tubes in India. These tubes are produced following the BS EN 10297-1 standard, which outlines technical delivery conditions for seamless circular tubes made from both non-alloy and alloy steels. They are widely used in mechanical and general engineering applications due to their strength and reliability.
The EN 10297-1 E355 grade indicates a minimum yield strength of 355 N/mm². The letter “E” signifies that the steel is suitable for manufacturing machine parts, while “AR” means no heat treatment is required. The tubes are made from killed steel, ensuring consistent quality and performance.
The EN 10297-1 seamless steel tubes can have a hot-finished rolled surface and contain 0.22% carbon, along with silicon, manganese, phosphorus, and sulfur in their composition. These tubes offer a minimum tensile strength of 490 MPa, which is higher than most austenitic steel grades, with an elongation of up to 20%.
These tubes are extensively used in industries such as petroleum, oil and gas, chemical, structural engineering, and power generation. They are also heat-treated to enhance their strength and provide a smooth surface, ensuring stable and efficient performance in various applications.
