ASTM A666-10

Standard Specification for Annealed or Cold-Worked Austenitic Stainless Steel Sheet, Strip, Plate, and Flat Bar

ABSTRACT
This specification covers austenitic stainless steels in the annealed and normally required cold-worked conditions. They shall be formed in different shapes such as sheets, strips, plates and flat bars. The steels shall adhere to specified chemical composition requirements. Mechanical properties such as yield strength, tensile strength, elongation, hardness, and bending shall be determined. The specimens shall be subjected to tension test, free-bend test, and controlled-bend or V-block test.
SCOPE
1.1 This specification covers austenitic stainless steels in the annealed and normally required cold-worked conditions for various structural, architectural, pressure vessel, magnetic, cryogenic, and heat-resisting applications. (This revision of Specification A666 replaces prior Specifications A412 and A177.)
1.2 The application of this specification, or the use of material covered by this specification does not automatically allow usage in pressure vessel applications. Only annealed conditions of grades specifically approved by the ASME code are permitted for pressure vessel use.
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.
