Low carbon steel, also known as mild steel, contains a low percentage of carbon, typically less than 0.3%. This composition makes it ductile and malleable, allowing it to be easily shaped and welded. It is commonly used in construction, automotive, and manufacturing industries due to its strength and affordability. Due to its low carbon content, low carbon steel is less prone to brittleness compared to higher carbon steels. However, it is also less hard and wear-resistant. Applications include structural beams, automotive body panels, and pipes, making it a versatile material in various engineering fields.
