For those looking for cost effective solutions Steelco manufactures hot rolled mild steel sheets, which are used in signs, automobiles, wire, fencing, furniture, nails, decorations and structural steel.
Hot rolling is a process where a material heated and processed above the recrystallization temperature. The initial material is usually large pieces of metal, which are fed directly into the rolling mills at the proper temperature. The material is worked and the temperature is kept above the recrystallization state. Hot-rolled metals in their mechanical properties and deformed states have little directionality.
Mild steel is a type of which has a low amount of carbon, known as low carbon steel as well. The amount of carbon found in mild steel usually vary from 0.05% to 0.25% by weight. Mild steel is not an alloy steel and therefore does not contain other elements apart from iron. Since its carbon and alloying element content are relatively low, there are several properties that it possesses which differentiate it from higher carbon and alloy steels. Mild Steel is typically more ductile, machine-able, and weld-able but cannot be strengthened or hardened by heating or quenching. The low carbon content also means that it has less tensile strength than high carbon and alloy steels. It also possesses a high amount iron and ferrite, making it magnetic.
The negligible amount of alloying elements makes mild steel relatively affordable when compared with other steels. This affordability, weld-ability, and machinability make it a popular choice for consumers.
The manufacturing of mild steel is quite similar to that of other carbon steels. A common method for this involves a combination of iron ore and coal. Upon extraction coal and iron ore are melted together in a blast furnace, where then in their combined melted state they are transferred to another furnace to burn off any impurities. It is also during this process that other adjustments to the mild steel’s chemical composition can be made. Following that, the steel is allowed to solidify into a rectangular slab. This slab of mild steel is then reduced to a desired size using processes called hot rolling or cold drawing.
