20MN Carbon Steel Tube/Pipe
20MN Carbon Steel Tube/Pipe is a tubular product made from a low-carbon structural steel that is alloyed with a controlled addition of manganese (Mn). This addition enhances the steel's strength, hardenability, and wear resistance compared to standard low-carbon grades. The "20" denotes a carbon content of approximately 0.20%. This pipe offers a good balance of moderate strength, toughness, and excellent weldability and formability. It is widely used in applications such as structural tubing, general machinery frames, and piping for non-corrosive fluids where moderate mechanical properties and good processability are required.
