| A-53 | This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26 [DN 6 to DN 650], inclusive, with nominal wall thickness. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser. |
| A-106 | This specification covers seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48 [DN 6 to DN 1200] inclusive, with nominal (average) wall thickness as given in ASME B 36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized. |
| A-108 | This specification covers cold-finished carbon and alloy steel bars produced in straight length and coil to chemical compositions. Cold-finished bars are suitable for heat treatment, for machining into components, or for use in the as-finished condition as shafting, or in constructional applications, or for other similar purposes. Grades of steel are identified by grade numbers or by chemical composition. |
| A-179 | This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. This specification covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. |
| A-213 | This specification covers seamless ferritic and austenitic steel boiler,superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. |
| A-214 | This specification covers minimum-wall-thickness, electric-resistance-welded,carbon steel tubes to be used for heat exchangers, condensers, and similar heat-transfer apparatus. Covers tubes 1/2 in. to 5 in. O.D. and 0.035 in. to 0.320 in. minimum wall thickness. |
| A-249 | This specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels, with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes. |
| A-269 | This specification covers grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resistance and low or high temperature service. |
| A-276 | This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. |
| A-312 | This specification covers seamless, straight seam welded and heavily cold worked welded austenitic stainless steel pipe intended for high temperature and general corrosive service. |
| A-500 | This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded,riveted, or bolted construction of bridges and buildings, and for general structural purposes. |
| A-511 | This specification covers seamless stainless tubing for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. |
| A-513 | This specification covers electric resistance welded carbon and alloy steel tubing for use as mechanical tubing. This specification covers mechanical tubing made from hot or cold rolled steel. This specification covers round, square, rectangular, and special shape tubing. |
| A-519 | This specification covers several grades of carbon and alloy steel seamless mechanical tubing. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service. |
| A-536 | This specification covers castings made of ductile iron, also known as spheroidal or nodular iron, that is described as cast iron with the graphite substantially spheroidal in shape and essentially free of other forms of graphite. |
| A-582 | This specification covers hot-finished or cold-finished bars, except bars for forging suitable for machining processes. It includes rounds, squares, and hexagons in the more commonly used types of stainless free-machining steels designed especially for optimum machinability and for general corrosion and high-temperature service |
