ASTM A 519 – Seamless Carbon and Alloy Steel Mechanical Tubing
Grade: 1541 (Higher Carbon Steels)
ASTM A 519 covers several grades of carbon and alloy steel seamless mechanical tubing. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components,and the intended service. This speciﬁcation covers both seamless hot-ﬁnished mechanical tubing and seamless cold-ﬁnished mechanical tubing in sizes up to and including 12 – 3/4 in. (323.8 mm) outside diameter for round tubes with wall thicknesses as required. The tubes shall be furnished in the following shapes, as speciﬁed by the purchaser: round, square, rectangular, and special sections.
