Low-carbon steel usually contains less than what percentage of carbon?

Low-carbon steel typically contains less than 0.35 percent carbon. This classification is important because the carbon content in steel significantly affects its properties, including strength, ductility, and weldability. Low-carbon steel, also known as mild steel, is characterized by its malleability and ductility, making it suitable for various construction and manufacturing applications.

The designation of low-carbon steel as containing less than 0.35 percent carbon aligns with industry standards, ensuring that the material is appropriate for tasks requiring flexibility and ease of fabrication. Steel with this composition is often used in structural applications, automotive parts, and general construction purposes where higher tensile strength is not a critical requirement.

Understanding the carbon content in steel types helps in selecting the right material for specific applications, ensuring optimal performance based on desired mechanical properties.
