Carbon Steel S235JR Round Bars

S235JR is a commonly used structural steel grade. It is a non-alloy carbon steel with a specified minimum yield strength of 235 megapascals (MPa). S235JR round bars are cylindrical bars made from the S235JR steel grade. They are often used in construction and engineering applications where high strength and good weldability are required.

The dimensions of S235JR round bars can vary, but they typically have diameters ranging from 10mm to 300mm. The available lengths of S235JR round bars can vary depending on the supplier and customer requirements. Common lengths include 3 meters, 6 meters, or customized lengths as per the customer's specifications.

The composition of S235JR steel typically includes carbon (C), manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), and small amounts of other elements. The specific composition may vary slightly depending on the manufacturing standards and processes.

The mechanical properties of S235JR steel include a minimum yield strength of 235 MPa, a minimum tensile strength of 360-510 MPa, and an elongation of 26% (in 200 mm). These values can vary depending on the heat treatment and other factors.

S235JR round bars find applications in various industries, including construction, engineering, manufacturing, and general metalworking. They are used for making structural components, machinery parts, shafts, axles, bolts, and other components requiring high strength and good formability.
