1、Designation: A276 10Standard Specification forStainless Steel Bars and Shapes1This standard is issued under the fixed designation A276; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthe
2、ses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers hot-finished or cold-finishedbars except bars
3、 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 s
4、eparate specification.NOTE 1For bars for reforging, see Specification A314.NOTE 2For free-machining stainless bars designed especially foroptimum machinability, see Specification A582/A582M.NOTE 3There are standards covering high nickel, chromium, austen-itic corrosion, and heat resisting alloy mate
5、rials. These standards are underthe jurisdiction of ASTM Subcommittee B02.07 and may be found inAnnual Book of ASTM Standards, Vol. 02.04.1.2 The values stated in inch-pound units are to be regardedas standard.
