Designation:A 276 -06#Stan dard Speci?catio n for1Stainless Steel Bars and ShapesThis standard is issued under the ?xed designation A 276; the number immediately following the designation indicates the year of original adoption or, in the caseof revision, the year of last revision. A number in parenthesesindicates the year of last reapproval.A superscript epsilon (e) indicates an editorial changesince the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.#1. Scope*1.1 This speci?cation covers hot-?nished or cold-?nished bars except bars for reforging (Note 1). It includes rounds, squares, and hexago ns, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types (Note 2) for gen eral corrosi on resista nee and high-temperature service are covered in a separate speci?cation.Note 1 For bars for reforging, see Speci?cation A 314.Note 2 For free-machining stainless bars designed especially for optimum machinability, seeSpeci?cation A 582/A 582M.Note 3 There are standards covering high nickel, chromium, austenitic corrosion, and heat resisting alloy materials. These standardsare under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol. 02.04.1.2 The values stated in inch-pound units are to be regarded as the standard.2.
