DIN 1628 ST37.4 WELDED STEEL TUBES, STEEL PIPES have a clear chemical composition, which contains up to 0.17% C, up to 0.35% S, at least 0.35% Mn, up to 0.040% P and S, and fixed N. The mechanical properties are excellent, with yield strength and other indicators varying for different wall thicknesses, e.g. for wall thicknesses up to 16 mm, the yield strength is a minimum of 235 N/mm², the tensile strength is 350-480 N/mm² and the elongation is a minimum of 25%.
DIN 1628 ST37.4 WELDED STEEL TUBES, STEEL PIPES have a number of advantages. First of all, their high strength and hardness enable them to withstand certain pressures and loads and to meet the strength requirements of a wide range of engineering structures. Secondly, with good plasticity and toughness, it is not easy to have brittle fracture during processing, such as bending, stretching and other operations, and can be processed into various shapes of complex components. In addition, the welding performance of the pipe is good, can be connected by conventional welding process, and the welded joints have high strength, to ensure the stability of the overall structure.
DIN 1628 ST37.4 WELDED STEEL TUBES,STEEL PIPES are mainly used in chemical plants, vessel construction, piping systems and general mechanical engineering. In chemical plants, they can be used in piping systems for the transportation of various chemical media, but the corrosiveness of the transported media should not be too strong. In the container manufacturing, such as the manufacture of some of the tanks to store common materials. In general mechanical engineering, can be used for the manufacture of mechanical structure of the support parts, drive shafts and so on. In pipeline engineering, it can be used to lay all kinds of industrial pipelines and civil pipelines, etc., but the use needs to be based on the specific working pressure and temperature and other conditions for a reasonable choice.
