Carbon Steel: Properties, Production, Examples and Applications

Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.

Types of carbon steel and their properties

Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel [1]. Their carbon content, microstructure and properties compare as follows:

PRODUCT DETAILS

A572 is a low-carbon, low-alloy high-strength steel coil produced employing the electric furnace steelmaking technology. So the main component is scrap iron. Owing to its reasonable composition design and strict process control, A572 steel coil is widely favored for high purity and excellent performance. Its molten steel pouring manufacturing method not only gives the steel coil good density and uniformity, but also ensures that the steel coil has superior mechanical properties after cooling. A572 carbon steel coil is widely used in construction, bridges, heavy machinery and other fields. At the same time, it performs well in welding, forming and corrosion resistance with its low carbon and low alloy characteristics.
