Lime acts as a flux and forms a protective layer on top of this hot molten metal.

In this leg of the steelmaking process, the iron ore is mixed with coal and lime and heated in a blast furnace having a 100 to 400-ton capacity. In modern manufacturing, three steps are involved in manufacturing mild steel out of pure iron. These processes have developed over time and are now much more cost-effective than before. Higher carbon steels just contain more carbon, resulting in different properties like high strength and hardness values compared to mild steel. The manufacturing processes for mild steel are similar to other carbon steels. This means that the metal becomes brittle and may fracture instead of bending when applying an excess load. As carbon content increases, steel develops hardness but loses ductility. How Is Low Carbon Steel Made?Ĭarbon content is uniformly increased by heat treating steel. Other elements are added to improve useful properties like corrosion resistance, wear resistance and tensile strength.

But they all have carbon content within the above-mentioned limits.

There are different grades of mild steel. Low carbon steels contain carbon in the range of 0.05 to 0.25 percent. The carbon content varies depending on the requirements for the steel. Carbon steels are metals that contain a small percentage of carbon (max 2.1%) which enhances the properties of pure iron. Mild steel is a type of low carbon steel.
