High Quality 
Mature Technical 
Safe and ST37 pipes are made of low-carbon steel. The chemical composition of the DIN 2391 ST37 Pipe is silicon, carbon, manganese, sulfur, and phosphorus. The design of these pipes makes them very resistant to corrosion and oxidation. The mechanical properties of the ST37 Seamless Pipe are very good.
