Also known as mild steel, this is a type of steel that contains a relatively low amount of carbon—typically between 0.05% and 0.25%. This makes it softer, more ductile, and easier to shape compared to higher carbon steels.
Some key characteristics include:

Machinability: It’s easy to work with and can be shaped through processes like welding, drilling, and cutting.
Strength: While it is not as strong as medium or high carbon steel, it still has good tensile strength and is suitable for many applications.
Corrosion Resistance: It is more prone to rusting or corrosion compared to higher carbon steels or stainless steels, though it can be treated with coatings or galvanized for better resistance.
Cost-Effective: Due to the low carbon content and the manufacturing process, it is relatively inexpensive and widely used.

Common uses of include construction materials (like beams and structural components), automotive parts, pipelines, and household items (such as nails, screws, and bolts). It is favored for applications where strength is not the primary requirement but where durability and ease of processing are important.
