1、Designation: A 313/A 313M 03Standard Specification forStainless Steel Spring Wire1This standard is issued under the fixed designation A 313/A 313M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number

2、 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.1. Scope*1.1 This specification covers austenitic and age-hardenablesta

3、inless steel round spring wire intended especially for themanufacture of springs.1.2 The values stated in inch-pound units or SI units are tobe regarded separately as the standard. Within the text andtables, the SI units are shown in brackets. The values stated ineach system are not exact equivalent

4、s; therefore, each systemmust be used independently of the other. Combining valuesfrom the two systems may result in nonconformance with thespecification.1.3 Unless the order specifies an “M” designation, thematerial shall be furnished to inch-pound units.2.
