1.1 This specification covers grades of stainless steel tubing in sizes under 1⁄2 down to
0.050 in. (12.7 to
1.27 mm) in outside diameter and wall thicknesses less than
0.065 in. down to
0.005 in. (1.65 to
0.13 mm) for general corrosion-resisting and lowor high-temperature service, as designated in Table 1. NOTE 1—The grades of austenitic stainless steel tubing furnished in accordance with this specification have been found suitable for lowtemperature service down to −325°F (−200°C) in which Charpy notchedbar impact values of 15 ft·lbf (20 J), minimum, are required and these grades need not be impact tested.
1.2 Optional supplementary requirements are provided and, when desired, shall be so stated in the order.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
