MILD STEEL ENGINEERING
Girders, bolts, nut, and screws are often made from this low carbon steel (it contains less than 0.3% carbon) and in many cases it is used as a substitute for wrought iron in decorative railings and gates.
Mild steel is very ductile, which means that it can take the stress of being bent or stretched without fracturing or breaking. From an engineering standpoint, this is a very important property for core materials because they must be able to withstand a high amount of stress. In structures such as tall buildings, which will actually sway, the ability of the core materials to withstand significant amounts of stress is imperative to the safety of the occupants.
Another very important property that makes mild steel one of the more desirable core materials is its malleability. Where ductility refers to the core material resisting breakage under tensile stress, malleability is its ability to be deformed under compressive stress without breakage. Compressive stress usually comes in the form of rolling or hammering the core materials into thin sheets. As compared to other types of steel, mild steel is an ideal material for welding because it can conduct an electric current without marring the surface of the metal.
