DIN 2391 ST37 Carbon Steel Seamless Pipes

DIN 17100 St 33 Welded Tube supplier

Standard DIN 2391 pipes are predominantly used in the automotive as well as mechanical engineering applications. Termed as seamless precision steel DIN 2391 ST37 Pipes are produced in compliance with ISO/DIN 3304. The dimensions of these pipes have been chosen from the range of manufacturing dimensions, which is why the DIN 2391 ST37 Carbon Steel Pipes could principally be used as design elements.

DIN standard 2391 makes use of low carbon steel grade ST37 in the manufacture of its products. With a carbon content of about 0.20%, the material is similar to grades S235JR or Q235. However, the material is neither as popular nor as strong in comparison to ASTM A36. Yet, many businesses work with these Carbon Steel DIN 2391 ST37 Tubes despite a lack of elevated strength, mainly because it is an affordable alloy. Like most alloys, the ST37 DIN 2391 Carbon Steel Seamless Pipes are available across markets either in a galvanized condition, black or pre-painted condition. While galvanization offers the highest resistance to corrosion, both pre-painting and coating with black oxide provides the Carbon Steel DIN 2391 Tubes with milder resistance to corrosion.
