1. Scope: 1.1 This specification covers seamless stainless steel tube for use in mechanical applications where corrosion-resistant or high-temperature strength is needed. The grades covered are listed in Table 1 and Table 2. 1.2 This specification covers seamless cold-finished mechanical tubing and seamless hot-finished mechanical tubing in sizes up to 12¾ in. [325 mm] in outside nominal diameter (for round tubing) with wall thicknesses as required. 1.3 Tubes shall be furnished in one of the following shapes, as specified by the purchaser: round, square, rectangular, or special. 1.4 Optional supplementary requirements are provided and when desired, shall be stated in the order. 1.5 The values stated in inch-pound units are to be regarded as the standard. Within the text, the SI units are shown in square brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. 2.

Small outside diameter tubes are defined as those under a 0.500 in. [12.7 mm] outside diameter and light-wall tubes as those under a 0.049 in. [1.2 mm] average wall thickness (0.044 in. [1.1 mm] min wall thickness). B The titanium content shall be not less than five times the carbon content and not more than 0.60 %. C The columbium plus tantalum content shall be not less than ten times the carbon content and not more than 1.00 %.4. Permissible Variations in Outside Diameter, Ovality, Wall Thickness, and Cut-Length Variations(Cold-Finished Round Tubing)AOutsideDiameter,in.Outside Diameter, Tolerance,Bin.
