DIN 1629 seamless steel pipes consist of three primary grades: St37.0, St44.0, and St52.0. Typically, the DIN 1629 standard does not impose restrictions on the working pressure value, while the working temperature is limited to below 300°C.
The DIN 1629 Pipe grades, including 37.0, 44.0, and 52.0, exhibit variations in material composition and mechanical properties. These grades find applications in manufacturing pipelines, vessels, equipment, pipe fittings, and other industrial uses. The DIN 1629 seamless steel pipe can undergo hot rolling, cold working, stress relief, annealing, or normalization for heat treatment to enhance product hardness.
