About Us

DIN 17172 Grade StE 290-7 pipes are high-strength, low-alloy steel pipes known for their robustness and versatility in various industrial applications. These pipes are designed to endure high pressure and mechanical stress, ensuring reliability in demanding conditions. They contain minimal alloying elements, which enhances their strength and toughness without compromising flexibility. Their excellent weldability makes them suitable for construction and engineering projects where strong joints are crucial.

 DIN 17172 Grade StE 290-7 Pipe Supplier

Amardeep Steel is a supplier of  DIN 17172 Grade StE 290-7 pipes, which are made from low carbon steel. These pipes are available in seamless or welded forms and can be left untreated or normalized.
