Mild steel and stainless steel are two of the most common types of steel. Depending on the percentage of carbon elements, the steel could be either mild or stainless. Mild steel is usually used for constructing buildings, railway tracks, bridges and mechanical machinery including ships, planes and vehicles. Stainless steel is typically used where corrosion of steel has to be reduced or completely eliminated.
The amount of carbon usually defines the properties of this type of steel. Other alloying elements such as manganese and chromium are not required to be added. Mild steel contains a very low percentage of carbon. Mild carbon steel has three types including high carbon steel, ultra high carbon steel and medium carbon steel. Ultra high carbon steel is extremely reliable as it can undergo heat treatment and therefore it is mostly used for constructing bridges and railway tracks.

Stainless steel is the most expensive type of steel as it contains the minimum amount of carbon. Furthermore it is used only when high corrosion resistance is required. Due to the lower carbon content, stainless steel offers high tensile strength, reliability and durability. Sometimes, alloying elements such as chromium are also added to form chromium oxide inert gas to tackle the corrosion problem. Stainless steel is also used in monuments, automobiles, machinery, bridges and buildings.
