DIN 2391 ST45 Carbon Steel Seamless pipe
ST45 steel pipe is a German seamless steel pipe material grade corresponding to China's 20# steel. This kind of steel pipe is made of low carbon steel, and its chemical composition includes C: 0.42~0.50, Si: 0.17~0.37, Mn: 0.50~0.80, S<0.035, P<0.035. This kind of steel pipe has balanced strength and toughness, as well as good processing ability and weldability, so it is widely used in communications, automobiles, home appliances, machinery manufacturing and other fields.
Within the German Industrial Standard DIN 2391, ST45 is a specific steel pipe grade. This steel pipe has a moderate wall thickness, a high internal surface finish, and a precision manufacturing process that allows it to withstand high temperatures and mechanical stress, while also providing good corrosion resistance and excellent strength properties. To meet the requirements of various usage conditions. In short, ST45 carbon steel pipe is a high-quality carbon structural steel with wide application prospects.
