What is ASTM A519?

  ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing. The standard is also acceptable in the manufacture of piping. It is manufactured by hot working and then cold finishing the steel into round, square, rectangle or special shapes.

Scope

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

  1.1 The frades anr listed in Tables 1, 2, and 3. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the frade, the condition of the components, and the intended service.

  1.2 This specification covers both seamless hot-finished emchanical tubing and seamless cold-finished mechanical tubing in sizes up to and including 12 3/4 in.(322.8mm) outside diameter of rround tubes with wall thicknesses as required.

  1.3 The tubes shall be furnished in the following shapes, as specified by the purchaser:round, square, rectagular, and special sections.

  1.4 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.
