ASTM A484/A484M-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: A484/A484M − 22 A484/A484M − 23
Standard Specification for
General Requirements for Stainless Steel Bars, Billets, and
1
Forgings
This standard is issued under the fixed designation A484/A484M; 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 (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
2
1.1 This specification 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 each of the following specifications issued by ASTM:
Specifications A276/A276M, A314, A458, A477, A479/A479M, A564/A564M, A565/A565M, A582/A582M, A638/A638M,
A705/A705M, and A831/A831M.
1.2 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.
1.3 The requirements for introduction of new materials in specifications referencing this specification are given in Annex A1.
1.4 General requirements for flat-rolled stainless steel products other than bar are covered in Specification A480/A480M.
1.5 General requirements for wire products in coils are covered in Specification A555/A555M.
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used
independently of the other, and values from the two systems shall not be combined.
1.7 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
