ASTM A519 1010 1020 High Precision Mechanical Tubing / Seamless Steel Pipe
Carbon Steel Tube ASTM A519 1010 1020 High Precision Tube Mechanical Tubing Seamless Steel Pipe
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.
Main steel grades: 1010,1020,1030,1035,1040...
Application: A519 seamless tubing is commonly used in applications requiring machining, heat treating, close tolerances, smooth finishes, and/or definite physical properties.
