In the realm of steel products, DIN17100 RSt37-2 seamless steel tubes occupy a pivotal position, renowned for their excellent mechanical properties and chemical composition. This article delves into the specifics of this steel grade, highlighting its unique features, applications, and TJC Steel Group's supply cases.

Chemical Composition

RSt37-2 seamless steel tubes adhere strictly to the DIN17100 standard, ensuring a precise chemical composition. The carbon content ranges from 0.17% to 0.20%, with manganese content below 1.4%. Phosphorus and sulfur are both kept below 0.045%, while silicon content is not specifically stipulated. This balanced composition ensures optimal performance in various applications.

Mechanical Properties

The mechanical properties of RSt37-2 seamless steel tubes are equally impressive. The tensile strength ranges from 340 to 470 MPa, with a minimum yield strength of 235 MPa. The elongation rate is at least 21.5%, demonstrating the material's excellent ductility. Additionally, the impact energy absorption, measured in Joules, is a minimum of 23 or 27, ensuring resistance to impact and sudden loading.

Heat Treatment and Dimensions

These steel tubes are commonly supplied in a hot-rolled, normalized, or controlled-rolled condition. The size range varies, with thicknesses typically ranging from a few millimeters to several centimeters, depending on the specific application. The tubes can be customized to meet specific length and diameter requirements.

Impact Testing

RSt37-2 seamless steel tubes undergo rigorous impact testing to ensure their resilience and durability. The average impact energy absorption value is used as the test result, with a minimum average of 23 or 27J. This ensures that the tubes can withstand sudden impacts without failing.

Applications

RSt37-2 seamless steel tubes find widespread applications in various industries. Their high strength, ductility, and weldability make them suitable for use in construction, machinery, automotive, and shipbuilding sectors. Additionally, their corrosion resistance and fatigue properties enhance their reliability in demanding environments.
