Carbon Steel ASME SA 519 Grade 1018 Tubing is a type of medium-low carbon seamless mechanical tubing that stands out for its impressive strength, toughness, and machinability. Shalan Steel, a top-notch manufacturer and supplier located in Kuala Lumpur, Malaysia, provides high-quality 1018 tubing that’s perfect for a wide range of industrial, mechanical, and structural uses. This tubing is popular throughout Malaysia and Southeast Asia, thanks to its great balance of strength and workability, along with consistent quality and precise dimensions.
Typically, Grade 1018 tubing has a carbon content of 0.15–0.20% and manganese content of 0.60–0.90%, which enhances its strength compared to lower carbon grades while still keeping good ductility. It boasts a tensile strength ranging from 440–620 MPa and a yield strength between 270–370 MPa. It responds well to heat treatments like carburizing or case hardening and is often supplied in cold-drawn or normalized states. Plus, 1018 tubing is known for its excellent weldability and ease of machining.
