20MN Carbon Steel Plate
20MN Carbon Steel Plate is a low-carbon structural steel that is primarily characterized by its controlled addition of manganese (Mn), which enhances its strength, hardenability, and wear resistance compared to plain carbon steel with lower Mn content (like standard 20# steel). The "20" generally denotes a carbon content of around 0.20%. This plate offers good weldability and formability and is typically used in the as-rolled or normalized condition. Due to its balance of strength and ductility, 20MN plate is widely used for general structural purposes, machinery parts, pressure vessel components, and construction elements where moderate strength is required.
