A572/S355JR Carbon Steel Coil Description
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.
