ST37 structural steel pipe is a German standard seamless steel pipe. Its material is ST37 and its execution standard is DIN1629 or DIN239112.
ST37 Structural seamless pipe has high strength and good toughness, and is suitable for the manufacturing of various structural parts, such as bridges, buildings, vehicles, machinery and other fields. In addition, it has excellent welding performance and processing performance, which facilitates various processing and connection operations.
The mechanical properties of ST37 Alloy Steel Seamless Pipes are also excellent, with a tensile strength of at least 420Mpa and a yield strength of no less than 315Mpa. Due to their seamless manufacturing nature, these pipes have no seams or welds during the manufacturing process, making them highly robust. Pipes are available in a wide range of external dimensions, from 4mm to 60mm, while wall thicknesses vary from 0.5mm to 8mm.
In addition, ST 37 NBK honing tubes play an important role in hydraulic systems. By polishing with wear-resistant rock, these pipes not only have exceptional hardness, but also have a very smooth surface. Therefore, ST37 pipe is widely used in various building structures, oil and gas refining, transportation and petrochemical industries.
