Product Description
DIN 1629 seamless steel pipes are circular tubes and pipes made up of non alloy materials for special quality requirements. There are three major grades as DIN 1629 ST 37.0, 44.0 and 52.0. The DIN 1629 Pipe grades differ in the material composition and the mechanical properties. The applications of the different grades of the DIN 1629 include manufacturing pipeline, vessels, equipment, pipe fittings and other applications. The DIN 1629 seamless steel pipe can be hot rolled, cold worked, stress relieved, annealed or normalized for heat treatment to improve the hardness of the products.
