The main chemical components are Fe and C, together with a small number of Si, Mn, P and S. The performances of carbon steel wire are depend on the amount of carbon content.The carbon steel wire can be classified into 3 groups accordingly to the carbon content inside.
Low Carbon Steel Wire: also known as mild steel wire, which contains 0.10% to 0.25% carbon. It is usually used for Chain, pin, bolt and shaft.
Medium carbon steel wire: It contains 0.25% to 0.60% carbon. It is applicated as construction material or used for mechanical parts.
High carbon steel wire: the common name is tool steel wire. It contains 0.60% to 1.7% carbon. The typical applications include drill, screw tap and so on.
With rising carbon content, the wire becomes stronger and harder, less ductile and quite difficult to weld. The higher carbon content also makes the metal less resistant to temperatures by lowering its melting point. Each of these types has specific uses because they differ in properties. For example, the high carbon steel wires are used to make drill bits, saws, masonry nails as well as wood and metal cutting tools.
