Abstract
The specification covers austenitic, stainless steel, needle tubing in hard-drawn tempers for industrial application. An electric furnace or other similar primary melting process with or without degassing or refining may be used. Needle tubing shall be made by the seamless or welded and drawn process and shall be furnished in the hard-drawn temper condition. Tension tests shall be made to meet the required tensile requirements.
Scope
1.1 This specification covers austenitic, stainless steel, needle tubing in hard-drawn tempers for industrial applications.
1.2 In general, needle tubing describes small-diameter tubing with outside diameters (ODs) in the range of 0.008 to 0.203 in. (0.2 to 5.2 mm) with nominal wall thicknesses in the range of 0.002 to 0.015 in. (0.05 to 0.4 mm). Needle tubing gages are normally 6 through 33.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
