ASTM A269/A269M-15

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope*
1.1 This 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.
1
1.2 The tubing sizes and thicknesses usually furnished to this specification are ⁄4 in. [6.4 mm] in inside diameter and larger and
0.020 in. [0.51 mm] in nominal wall-thickness and heavier.
1
1.3 Mechanical property requirements do not apply to tubing smaller than ⁄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.
1.4 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated in
the order.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units
are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used
independently of the other. Combining values from the two systems may result in non-conformance with the standard. The
inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
