How S275 is Made
S275 is made in a fashion similar to most carbon steels. First, iron ore and coal are combined in a furnace. Impurities are burned away and alloying elements are added to the molten steel. Once the chemical composition of the S275 steel is achieved, it is solidified in into a rectangular ingot. S275 steel is normally hot rolled. This means that it is formed to its final dimensions in using rollers while the ingot is at an elevated temperature.
S275 steel is used in many different industries for a variety of applications because of its relatively low cost. As mentioned, the mechanical properties make it particularly suited for structural applications. Many bridges are constructed with S275 steel. Likewise, buildings are frequently created with S275 steel because of its high strength and toughness. S275 steel is also used for components in the automotive, construction, heavy equipment, and oil and gas industries.
