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.ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished.
This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties.
The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
