What is Carbon Steel Round Bar?

Carbon Steel Round Bars consist mainly of iron and carbon, and the carbon percentage is usually between 0.05% and 2.0%. On the basis of the grade, they can also have small amounts of manganese, sulfur, and phosphorus. They are renowned for their superior tensile strength, ductility, and hardness. The mechanical properties differ according to type but typically consist of a tensile strength of 400-800 MPa and impact resistance. They are thus appropriate for heavy-duty usage where there is a need for both strength and machinability in demanding conditions.
