ASTM A519/A519M

ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing.

ASTM A519 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.


Size range(mm):

Out diameter:10-324mm
Wall Thickness:1-30mm

Length:14000mm max
