About Us

EN 10210-1 Grade S275NH Carbon Steel Pipe is a type of mild steel pipe used for structural applications. These pipes are known for their low carbon content, making them easy to form and machine. The carbon content in these pipes is about 0.2%, and they also include elements like silicon, manganese, phosphorus, and sulfur in their composition.

The presence of 1.4% manganese in the alloy improves the material's formability and machinability. Additionally, these pipes are resistant to corrosion, which makes them suitable for use in various environments where corrosion could be a concern. The hot finished variant of these pipes provides even better corrosion resistance due to its special finish.

The EN 10210-1 Grade S275NH European standard specifies the requirements for hot-formed or annealed hollow sections made from construction steel. These pipes are supplied in lengths ranging from 5 to 7 meters, with butt-weld ends and a varnished coating to prevent oxidation during storage. Each pipe is fully certified and traceable, with heat numbers hard stamped onto each length for identification.

EN 10210-1 Grade S275NH Carbon Steel Pipe Supplier 

Amardeep Steel is a leading manufacturer and supplier of EN 10210-1 Grade S275NH pipes, we produce them with a minimum yield strength of 275MPa and a minimum tensile strength of 530MPa. The specifications of these seamless tubes vary according to DIN, EN, BS, NFA, ASTM, and ASME standards. 

Please feel free to contact us for more information and pricing on EN 10210-1 S275NH welded pipes and other grades.

EN 10210-1 Grade S275NH pipes and tubes are available in various dimensions, finishes, and lengths. The wall thicknesses range from 10.2mm to 1219mm, and the lengths range from 5m to 7m. These pipes are made of low carbon steel, mild steel, making them ideal for structural applications.

With a carbon content of 0.2%, the composition also includes silicon, manganese, phosphorus, and sulfur. The presence of 1.4% manganese enhances the formability and machinability of the EN 10210-1 Grade S275NH carbon steel seamless pipes and tubes. 

EN 10210-1 Grade S275NH pipes are corrosion-resistant and suitable for general corrosive environments. The hot-finished tubes offer even better corrosion resistance due to their special finish. These strong pipes are widely used in structural and mechanical engineering, as well as in the petroleum, petrochemical, and food processing industries.
