DIN2391 ST37 Carbon Steel Precision Pipe
Cold drawn precision seamless steel pipe
ST37 seamless steel pipe, a carbon steel pipe that meets DIN 2391 standards, has a unique chemical composition that determines its excellent mechanical and process properties. Its main elements include carbon, manganese, silicon, phosphorus and sulfur. Although it contains trace amounts of chromium, copper, nickel and molybdenum, its total content is extremely low, no more than 0.30%. This enables ST37 seamless precision steel pipes to be widely used in various industrial fields, such as construction, bridges, vehicle manufacturing, shipbuilding industry, and pressure vessels.
