Low-carbon steel is a type of carbon steel with low carbon content, typically referring to steel materials with a carbon content ranging from 0.02% to 0.30%. Due to its low carbon content, it is also known as “mild steel.”

Its performance characteristics are particularly notable: compared to medium-carbon steel and high-carbon steel, although its strength is relatively lower , it exhibits excellent ductility, plasticity, and toughness. Additionally, it is easy to form through processes such as rolling, stamping, and welding. Moreover, it boasts excellent weldability and is less prone to welding cracks.

Owing to these properties, low-carbon steel is widely used in industrial fields.
