The surface of stainless steel that has been pickled is free of scale, free iron, and exogenous foreign matter, and does not require a separate treatment for passivation as de? Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel. The cloth pad used shall be used for only one such test, being changed for each test so as to avoid risk of contamination.

ASTM A – 05 Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts
Such treatments, also sometimes called passivation in common usage, are designated as post-cleaning treatments in this speci? Precision and Bias Materials and Preparation for Passivation Treatments 5.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Rinsing can be accomplished by astn combination of stagnant, countercurrent or spray rinses, or both, prior to?
At the end of this period, the surface shall be carefully rinsed and dried with care taken not to disturb copper deposits if present.
ASTM A967 Passivation Standard
This standard does not purport to address all of the safety concerns, if any, associated with its use. The cloth shall be in contact with the steel for an area of at least 20 square inches cm2. Stainless steel passivation performed to the ASTM A standards meets these standards by passing tests that confirm its effectiveness, particularly as it pertains to removing 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? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Such records shall be available for inspection when speci? The test solution shall be mixed fresh on the day of the test. The standards that collectively make up the ASTM A passivation specification ensure that nitric and citric stainless steel passivation is performed properly and with quality results. Not all of the following tests are suitable for all grades of stainless steel.
By meeting standards set by the ASTM and other organizations, we can ensure consistently-high quality for a broad range of metal parts across many industries. This standard is subject to revision at any time by the responsible technical committee and must be a9667-05 every? Link to Active This link will always route to the current Active version of the standard.
The processor is not required to reveal the precise composition of proprietary chemical mixtures but shall maintain a unique identi? Active view current version of standard.
NOTE 2—Some of the tests may produce positive indications not associated with the presence of free iron on the stainless steel surface. Asmt electrochemical cleaning is required, it shall be performed in accordance with Practice B An example of a medium that serves to accelerate the formation of the passive?
These tests include the following practices:. The pad shall be maintained wet through the test period, either by a method of retarding external evaporation, by the further addition of potable water, or by backing the pad with a a967–05 or similar water source. This test is not recommended for detection of asstm iron on ferritic or martensitic series stainless steels, because these steels will give a positive indication irrespective of the presence or absence of anodic surface contaminants.
Practice A—Water Immersion Test All samples must pass the speci?
It includes several alternative tests, with acceptance criteria, for astj This standard does not purport to address all of the safety concerns, if any, associated with its use.
Current edition approved Sept. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
