A572/S355JR 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.
