ASTM A276 Standard Specification for Stainless Steel Bars and Shapes1

A276 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 free-machining types for general corrosion resistance and high-temperature service are covered in a separate specification.

Manufacture

Condition:
Bars shall be furnished in one of the following conditions listed in the Mechanical Requirements table:

  • Condition A - Annealed.
  • Condition H - Hardened and tempered at a relatively low temperature.
  • Condition T - Hardened and tempered at a relatively high temperature.
  • Condition S - Strain Hardened-Relatively light cold work.
  • Condition B - Relatively severe cold work.
  • Condition SA - Stabilized annealed.

B Temperature tolerance is ±25°F [14°C].

Chemical Composition

The steel shall conform to the requirements for chemical composition specified in Table.
Methods and practices relating to chemical analysis required by this specification shall be in accordance with Test Methods, Practices, and Terminology A751.

Note:
A Maximum, unless range or minimum is indicated. Where ellipses (. . .) appear in this table, there is no requirement and the element need not be determined or reported.
B Designations established in accordance with Practice E527 and SAE J1086.
C For some applications, the substitution of Type 304L for Type 304, or Type 316L for Type 316 may be undesirable because of design, fabrication, or service requirements. In such cases, the purchaser should so indicate on the order.
D Nitrogen content is to be reported for this grade.
E % Cr + 3.3 × % Mo + 16 × % N $ 40.
F Nickel plus copper shall be 0.50 % max.
G Product analysis tolerance over the maximum limit for carbon and nitrogen shall be 0.002 %.
H Wrought version of CA 6NM.
I Iron shall be determined arithmetically by difference of 100 minus the sum of specified elements.
J (Al + Ti) = 0.85 - 1.20.
K The terms Columbium (Cb) and Niobium (Nb) both relate to the same element.
L % Cr + 3.3 × % Mo + 16 × % N $ 41.

Mechanical Properties

The material shall conform to the mechanical test requirements specified in Table
The martensitic grades shall be capable of meeting the hardness requirements after heat treating as specified in Table.
Hardness measurements, when required, shall be made at a location midway between the surface and the center of the cross section.

Note:
A Yield strength shall be determined by the 0.2 % offset method in accordance with Test Methods and Definitions A370 or Test Methods A1058. 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 A370 or Test Methods A1058.
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.
D The 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 (HRB or HRC).
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 HBW when oil quenched from 1750°F [950°C].
