Carbon Steel Seamless Pipe
Details of Carbon Steel Seamless Pipe
What is a Carbon Steel Seamless Pipe?
Carbon steel seamless pipes are also called CS pipes. The general carbon steel seamless pipe is made of 10, 20, 30, 35, 45, and other high-quality carbon steel 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB, and other alloy steel hot-rolled or Cold rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid conveying pipes. 45, 40Cr and other medium carbon steel seamless pipes are used to make mechanical parts, such as the force parts of automobiles and tractors.
