ASTM A519-89/ASME SA519 Material comparison tables

Seamless mechanical tubing is manufactured from carbon and alloy steels for structural or other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors.

• ASTM A519-89/ASME SA519 Standard specification

Scope

1.1 this specification covers several frades of carbon and alloy steel seamless mechanical tubing. 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.

1.5 The values stated in inch-pround units are to be regarded as the standard.

Application:

• For mechanical engineering.
• For mechanical and pressure use,and also for transporting steam,water,gas and etc.
