Dang Steel, based in Da Nang, Vietnam, stands out as a top manufacturer and supplier of precision-engineered steel products, providing a wide array of carbon steel solutions tailored to various industrial needs. One of their standout products is the Carbon Steel DIN 2391-2 Pipe, which adheres to strict German standards for seamless precision steel tubes used in mechanical, automotive, and hydraulic applications. Renowned for its remarkable dimensional accuracy, smooth internal surfaces, and high-performance features, Dang Steel guarantees that all DIN 2391-2 pipes go through thorough quality control. The company caters to clients throughout Southeast Asia and beyond, consistently delivering reliable and cost-effective steel tubing solutions.
When it comes to the composition and mechanical properties of Carbon Steel DIN 2391-2 Pipes, they are generally crafted from low-carbon steel grades like St 35, St 45, and St 52. These grades have carbon content ranging from 0.10% to 0.22%, with manganese levels reaching up to 1.6%, along with trace amounts of silicon, phosphorus, and sulfur. The mechanical properties showcase tensile strength between 340–630 MPa and yield strength from 235–355 MPa, depending on the specific grade. These pipes are known for their excellent elongation (≥21%), consistent wall thickness, and superior internal surface finish, making them perfect for high-precision applications that demand strength, ductility, and outstanding machinability.
