ASTM A276-05a

Standard Specification for Stainless Steel Bars and Shapes

SCOPE
1.1 This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1). It includes rounds, squares, and hexagons, 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 general corrosion resistance and high-temperature service, are covered in a separate specification.
Note 1—For bars for reforging, see Specification A 314.
Note 2—For free-machining stainless bars designed especially for optimum machinability, see Specification A 582/A 582M.
Note 3—There are standards covering high nickel, chromium, austenitic corrosion, and heat resisting alloy materials. These standards are under the jurisdiction of ASTM Subcommittee B 02.07 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.
