ASTM A632-02a

Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing (Small-Diameter) for General Service

SCOPE
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 low- or 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 low-temperature service down to 325°F (200°C) in which Charpy notched-bar impact values of 15 ftlbf (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 the standard.
