Carbon steel can be classified into three main categories: low carbon steel, moderate carbon steel, high carbon steel.
Low Carbon Steel (Mild Steel):
Usually made of 0.04 to 0.30 percent carbon content; low carbon content contributes to its high strength From Flat Sheet to Structural Beams-the variety of shapes of mild steel is impressive Various elements can be incorporated to create new steel products. For structural steel, the quality of coal and manganese is increased. The ductility of mild steel is second to none. Under stress, mild steel bends and deforms, while higher carbon steels shatter or crack. Due to its high ductility, mild steel is a versatile tool for building. It ensures it can be quickly reshaped to tougher steels, which is not possible. Welding to itself and certain forms of steel is also simpler.
Medium Carbon Steel:
Usually, it has a carbon content varying from 0.31% to 0.60% and a manganese content ranging from 0.060% to 1.65%. Low carbon iron, heavier and easier to mold, weld, and break. By heat processing, medium carbon steels are often strengthened and tempered.
High Carbon Steel:
High carbon steel has a carbon content of 0.61% to 1.50%. Cutting, twisting or welding is very difficult. It becomes extremely hard and fragile once the heat is treated, making it completely unsuitable for construction work.
