ASTM F1058-16

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: F1058 − 08 F1058 − 16
Standard Specification for
Wrought 40Cobalt-20Chromium-16Iron-15Nickel-
7Molybdenum Alloy Wire Wire, Strip, and Strip Bar for
Surgical Implant Applications (UNS R30003 and UNS
1
R30008)
This standard is issued under the fixed designation F1058; 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.
1. Scope*
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for two grades of wrought 40cobalt-
20chromium-16iron-15nickel-7molybdenum alloy in the form of wire wire, strip and stripbar used for the manufacture of surgical
implants.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The inch-pound equivalents
of the SI units in parentheses are for information only.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.
