Carbon Seamless Steel Tubing ASTM A519 1018 1026 Hot Finished Or Cold Finished Tubing
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.
