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 ft·,lbf (20 J), minimum, are required and these grades need not be impact tested.
