Thabiso Steel, based in Cape Town, South Africa, has built a solid reputation as a reliable manufacturer and supplier of top-notch steel products tailored for industrial and mechanical uses. Among its specialized offerings is the Carbon Steel ASME SA 519 Grade 1518 Tubing, a seamless mechanical tubing designed for exceptional strength, precision, and durability. Crafted in line with ASME standards, this tubing is perfect for applications in the automotive, agricultural, and general engineering fields. Thabiso Steel is dedicated to providing high-quality materials that perform reliably, ensuring that customers receive technically sound solutions along with responsive service and consistent quality throughout Southern Africa and beyond.
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.
