Carbon Steel


Advantages and disadvantages of carbon steel, as well as the range of mechanical properties:

1. High strength: Carbon steel exhibits high strength and can withstand most common stresses and loads.
2. Good formability: Carbon steel is easy to process and shape, suitable for various manufacturing methods such as forging, stamping, and welding.
3. Relative low cost: Carbon steel is generally less expensive compared to some alloy steels and stainless steels.
4. Good weldability: Carbon steel is easy to weld, making it suitable for applications that require welding connections.

1. Susceptible to corrosion: Carbon steel is prone to rusting and corrosion in humid or corrosive environments, requiring protective measures.
2. Lower heat resistance: Compared to some high-temperature materials, carbon steel has poorer heat resistance and is susceptible to softening and deformation.
3. Lack of special properties: Compared to some alloy steels, carbon steel may have inferior performance in special properties such as corrosion resistance and wear resistance.

Range of mechanical properties:
The range of mechanical properties for carbon steel can vary depending on factors such as carbon content and treatment conditions. Generally, the tensile strength of carbon steel can range from 370 to 1,040 MPa, the yield strength from 250 to 650 MPa, and the elongation typically varies between 5% and 25%. These values are provided as a reference and actual values are influenced by carbon content, heat treatment, and microstructure. Different grades of carbon steel with varying carbon content can be selected and applied based on specific usage requirements.
