ASTM A276-08a

Standard Specification for Stainless Steel Bars and Shapes

ABSTRACT
This specification covers hot-finished or cold-finished bars except bars for reforging. 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 bars shall be furnished in one of the following conditions: Condition A in which the bars are annealed, Condition H in which the bars are hardened and tempered at a relative temperature, Condition T in which the bars are hardened and tempered at a relatively high temperature, Condition S in which the bars are strain hardened or relatively light cold worked, and Condition B in which the bars are relatively severe cold worked. The material shall be subjected to a mechanical test to determine its tensile strength, yield strength, elongation, and Brinell hardness.
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 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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
