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 . Their carbon content, microstructure and properties compare as follows:

PRODUCT DETAILS



A572  Round Steel Bar Description
A572 steel bar is made of a low-carbon, low-alloy  high-strength steel employing the electric furnace steelmaking technology. So the main component is scrap  iron. Resulting from its reasonable composition design and strict process control,  A572 steel bar 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 bar has superior mechanical properties after cooling. A572 carbon steel bar is  widely used in construction, bridges, heavy machinery and other fields. At  the same time, it shows outstanding performance in welding, forming and  corrosion resistance with its low carbon and low alloy characteristics.
