The DIN 2391 Grade St45 Seamless Pipe is, therefore, the product of choice where dimensional integrity is not a preference but a safety and performance prerequisite. Its use underpins the reliable operation of sensitive mechanical and fluid systems across every facet of modern industry, providing a foundational component that assures precision from the manufacturing stage all the way to decades of operational service.
We focus on continually improving the quality of our processes. With recent investments in an intermediate finishing line, water-blast descaling process, and continuous induction thermal treat facility, we strengthened our ability to offer quality, customized solutions. Our approach to manufacturing integrates our melting, rolling, piercing and finishing operations, helping to ensure quality control from start to finish. Our seamless mechanical tubing processes include piercing (rotary forging), thermal treatment, and testing and finishing.
Mechanical steel tubes are essential for a variety of industrial applications requiring high strength, precision, and durability. The choice of material—whether carbon steel, alloy steel, or stainless steel—depends on the specific requirements of the application, such as mechanical properties, corrosion resistance, and ease of machining.
