A572/S355JR Round Steel Bar

Short Description:

A572 steel bar is a low-carbon, low-alloy high-strength steel produced by electric furnace steelmaking process. Its main component is scrap iron. Reasonable component design and strict process control make it high in purity and excellent in performance. The molten steel casting manufacturing method makes it have good density and uniformity, and ensures that the steel bar has excellent mechanical properties after cooling. It is widely used in construction, bridges, heavy machinery and other fields. At the same time, its low-carbon and low-alloy characteristics make it perform well in welding, forming, corrosion resistance and other aspects.
