Designation: A 276 – 06
Standard Specification for
Stainless Steel Bars and Shapes1
This standard is issued under the fixed designation A 276; the number immediately following the designation indicates the year of
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 (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

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 the standard.

SUMMARY OF CHANGES
Committee A01.17 has identified the location of selected changes to this standard since the last issue,
A 276 – 05a, that may impact the use of this standard. (Approved March 1, 2006.)
(1) Added 304L and 316L to Table 2 for condition B and
condition S.

A Yield strength shall be determined by the 0.2 % offset method in accordance with Test Methods and Definitions A 370. An alternative method of determining yield
strength may be used based on a total extension under load of 0.5 %.
B For some specific products, it may not be practicable to use a 2-in. or 50-mm gage length. The use of sub-size test specimens, when necessary, is permissible in
accordance with Test Methods and Definitions A 370.
C Reduction of area does not apply on flat bars 3⁄16 in. (4.76 mm) and under in thickness as this determination is not generally made in this product size.
DThe material shall be capable of meeting the required reduction of area where listed, but actual measurement and reporting of the reduction of area are not required
unless specified in the purchase order.
E Or equivalent Rockwell hardness.
F For extruded shapes of all Cr-Ni grades of Condition A, the yield strength shall be 25 ksi (170 MPa) min and tensile strength shall be 70 ksi (480 MPa) min.
G For shapes having section thickness of 1⁄2 in. (12.5 mm) or less, 30% min. elongation is acceptable.
H Material shall be capable of being heat treated to a maximum Brinell hardness of 250 when oil quenched from 1750°F (953°C).
