Carbon Steel ASME SA 519 Grade 1518 Tubing, intended for precise mechanical and structural applications, is proudly offered by Luke Steel, a top steel manufacturer and supplier with headquarters in Houston, USA. This seamless carbon steel tubing is renowned for its strength, adaptability, and superior machinability and is manufactured in compliance with the strict ASME SA 519 standards. Quality, accuracy, and performance are our top priorities at Luke Steel, and we make sure every tube satisfies stringent material and dimensional requirements. For crucial applications in the hydraulic, industrial, and automotive sectors where accuracy and longevity are crucial, our Grade 1518 tubing is perfect.
About 0.15–0.21% carbon, 1.10–1.50% manganese, and trace amounts of phosphorus and sulphur make up ASME SA 519 Grade 1518 Tubing. With tensile strengths between 485 and 620 MPa and yield strengths between 275 and 380 MPa, this medium carbon steel demonstrates exceptional strength and resistance to wear. After heat treatment, it also provides good hardness and ductility. For demanding mechanical and structural environments, Grade 1518 tubing, whether supplied normalised, cold-drawn, or quenched and tempered, guarantees dimensional stability and mechanical dependability.
