ASTM A36 Round Bar
A36 round steel is a type of carbon structural steel that complies with ASTM production standards. Its yield strength is greater than or equal to 250MPa, and its tensile strength is between 400MPa and 550MPa. It is used to manufacture welded and bolted metal structures for industrial and civil buildings and bridge buildings. A36 round steel has high strength and high toughness, and is often used in mechanical equipment and precision machinery manufacturing, as well as precision parts processing.

What are the advantages of round steel?
High strength: steel round bar is hot-rolled or cold-drawn, which has high strength and load-bearing capacity and can withstand large loads and stresses.
Good plasticity: round stock steel has good plasticity, can be bent, straightened and other processing, easy to adapt to the needs of various shapes.
Corrosion resistance: round stock metal has good corrosion resistance after anti-rust treatment, which can be used in some corrosive environments.
Easy to process: round bar stock steelcutting, grinding, drilling and other processing is relatively easy, low processing costs.
