What is Carbon Steel ASME SA 519 Grade 1518 Tubing?
The Carbon Steel ASME SA 519 Grade 1518 Tubing is a low-alloy, seamless mechanical steel tubing that contains about 0.15–0.21% carbon and 0.60–0.90% manganese. It strikes a great balance between machinability, strength, and ductility. Its mechanical properties feature a tensile strength typically ranging from 485–620 MPa and a yield strength around 275 MPa, depending on the heat treatment applied. This tubing grade is well-suited for cold drawing and other forming processes, boasting good weldability and a smooth surface finish. It is often supplied in a normalized or annealed state and can be further heat-treated to meet more stringent performance requirements.
