Designation:A 313/A 313M –03
Standard Specification for
Stainless Steel Spring Wire 1
This standard is issued under the fixed designation A 313/A 313M;the number immediately following the designation indicates the year of original adoption or,in the ca of revision,the year of last revision.A number in parenthes 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 u by agencies of the Department of Defen.
1.Scope*
1.1This specification covers austenitic and age-hardenable stainless steel round spring wire intended especially for the manufacture of springs.
1.2The values stated in inch-pound units or SI units are to be regarded parately as the standard.Within the text and tables,the SI units are shown in brackets.The values stated in each system are not exact equivalents;therefore,each system must be ud independently of the other.Combining values from the two systems may result in nonconformance with the specification.
1.3Unless the order specifies an “M”designation,the material shall be furnished to inch-pound units.
