This specification2 covers general requirements that
shall apply to wrought stainless steel bars, shapes, forgings, and
billets or other semi-finished material (except wire) for forging,
under the latest revision of each of the following ASTM
specifications: A276, A314, A458, A473, A477, A479/ A479M,
A564/A564M, A565/A565M, A582/A582M, A638/ A638M, A705/A705M, and
In the case of conflict between a requirement of a product
specification and a requirement of this specification, the product
specification shall prevail. In the case of conflict between a
requirement of the product specification or a requirement of this
specification and a more stringent requirement of the purchase
order, the purchase order shall prevail. The purchase order
requirements shall not take precedence if they, in any way, violate
the requirements of the product specification or this
specification; for example, by waiving a test requirement or by
making a test requirement less stringent.
The requirements for introduction of new materials in
specifications referencing this specification are given in Annex
General requirements for flat-rolled stainless steel products
other than bar are covered in Specification A480/A480M.
General requirements for wire products in coils are covered in
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
Unless the order specifies an “M” designation, the material
shall be furnished to inch-pound units.
