Hot Rolled Carbon Steel Round Bars

Product Description
According to the different uses and materials, steel round bars can be divided into ordinary carbon steel and high-quality carbon steel, as well as hot rolled, forged and cold drawn three types.
Ordinary carbon steel has wider limits on carbon content, performance range and the content of phosphorus, sulfur and other residual elements, while high-quality carbon steel has lower content of sulfur, phosphorus and other nonmetallic inclusions.



Round steel bars is mainly used in the manufacture of mechanical parts, ‌ bearing, ‌ automobile and other industries, with high strength, high wear resistance and good mechanical properties, suitable for all kinds of engineering structures and tool manufacturing. ‌
