Designation: A276/A276M − 17Standard Specif i cation forStainless Steel Bars and Shapes 1This standard is issued under the f i xed designation A276/A276M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specif i cation covers hot-f i nished or cold-f i nishedbars except bars for reforging (Note 1). It includes rounds,squares, and hexagons, and hot-rolled or extruded shapes, suchas angles, tees, and channels in the more commonly used typesof stainless steels. The free-machining types (Note 2) forgeneral corrosion resistance and high-temperature service arecovered in a separate specif i cation.N OTE 1—For bars for reforging, see Specif i cation A314.N OTE 2—For free-machining stainless bars designed especially foroptimum machinability, see Specif i cation A582/A582M.N OTE 3—There are standards covering high nickel, chromium, auste-nitic corrosion, and heat-resisting alloy materials. These standards areunder the jurisdiction of ASTM Subcommittee B02.07 and may be foundin Annual Book of ASTM Standards, Vol. 02.04.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard. The inch-pound units shall apply unless the “M”designation of this specif i cation is specif i ed in the order.2.
