DIN 1629 ST 52 Pipe
Aesteiron Steels LLP is can supplies DIN1629 steel from the reputed steel manufacturers. And also offer steel fabrication service where it can go through processing like cutting in any size and any shape, welding, drilling, milling, machining as per the customers requirement.
DIN 1629 is made up of unalloyed steel, and it can be manufactured with no limiting working pressure values. Its main grades are DIN 1629 ST 35, DIN 1629 ST 52, and DIN 1629 ST37.
DIN 1629 ST 35 can be manufactured from either electric steel or from basic oxygen steel.
DIN 2391 ST 37 can be processed as hot rolled, cold rolled, cutting, grinding, machining and forming operations. It has high impact strength due to which it can be used under high impact prone outdoor applications as well.
DIN 1629 ST 52 is a low-cost Low Carbon Steel Tubes with max 022 % carbon content easy to form and shape. It is suitable for gas fusion welding, arc welding, flash butt welding, electric pressure welding and gas pressure welding. DIN 1629 part 3 is not only hard, but it also has high tensile properties, which is expected for structural components. It has good weldability properties with its pre-existing chemistry.
