20MN Carbon Steel Coil/Strip
20MN Carbon Steel Coil/Strip is a rolled thin-gauge product made from a low-carbon structural steel characterized by its controlled addition of manganese (Mn). This Mn content enhances the material's strength, hardenability, and wear resistance compared to standard low-carbon steel. The "20" denotes a carbon content of around 0.20%. This coil or strip offers good weldability, excellent formability, and stamping properties, making it highly suitable for high-volume manufacturing processes. 20MN coil/strip is widely used for producing structural tubing, cold-formed parts, automotive components, and various machinery parts where moderate strength, reliability, and ease of cold working are required.
