Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Originally approved in June 11—13, Chicago, IL. Not all of the following tests are suitable for all grades of stainless steel. Such treatments may include externally applying an electrical potential on the stainless steel parts, as in the case of electropolishing. Stainless steel passivation performed to the ASTM A standards meets these standards by passing tests that confirm its effectiveness, particularly as it pertains to 9a67 free iron from the cold-worked surfaces.
The effectiveness of a particular treatment for a particular grade of stainless steel in a particular application is demonstrated by meeting the speci?

QQ-PC, but also includes a number of alternative passivation treatments. Stainless Steel Passivation and More Able Electropolishing provides metal passivation services that meet the ASTM A standards, as well as other finishing treatments that improve the corrosion resistance of stainless steel and various other alloys. Attention shall be given to maintaining adequate volume, concentration, purity, and temperature control appropriate to the size and amount of stainless steel to be treated.
Practice F—Free Iron Test A rejected lot may, at the option of the processor, be re-passivated, with or without re-pretreatment, and then be retested. Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel.
Statements regarding chemical treatments, unless otherwise speci? It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts. The test a9677 shall be mixed fresh on the day of the test.
