  ASTM A513 and A519 mechanical tube are both American Society for Testing and Materials (ASMT) standard specifications for the manufacture of mechanical tube. Both cover carbon and alloy steel tubing, but there are some key differences.

  ASTM A513 specification covers round, square, rectangular, and special shape electric-resistance-welded carbon and alloy steel mechanical tubing produced by hot- or cold-rolling. The types of tubing covered here are: Type 1a, as-welded from hot- rolled steel (with mill scale); Type 1b, as-welded from hot-rolled pickled and oiled steel (mill scale removed); Type 2, as-welded from cold-rolled steel; Type 3, sink-drawn hot-rolled steel ; Type 4, sink-drawn cold-rolled steel; Type 5, drawn over a mandrel; and Type 6, special smooth inside diameter.

  A519 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.
