ASTM A269 Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service

ASTM A269 Standard Specification covers grades of nominal-wall thickness, stainless steel tubing for general corrosion-resisting and low- or high-temperature service, as designated in Table 1. 

The tubing sizes and thicknesses usually furnished to this specifification are 1⁄4 in. (6.4 mm) in inside diameter and larger and 0.020 in. (0.51 mm) in nominal wall-thickness and heavier. 

Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. (3.2 mm) in inside diameter or 0.015 in. (0.38 mm) in thickness. NOTE 1—Additional testing requirements may apply for use in ASME B31.3 applications. 

Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated in the order. 

The values stated in inch-pound units are to be regarded as the standard.
