Carbon Seamless Steel Tubing ASTM A519 1018 1026 Hot Finished Or Cold Finished Tubing
The ASTM A519 steel tube specification covers both hot-finished and cold-finished mechanical tubing in sizes up to 12-3/4” O.D. A519 is available in round, square, and rectangular profiles, and in special sections.
Stamdard: ASTM A519
Main steel grades: 1008,1010,1020,1025,1026
Application: A519 seamless tubing is commonly used in applications requiring machining, heat treating, close tolerances, smooth finishes, and/or definite physical properties.
