Lot, Frequency of Testing, and Selection of Test Minor changes have been made in the text to facilitate references to the main document and to correct technical inaccuracies. Practice B—High Humidity Test NOTE 2—Some of the tests may produce positive indications not associated with the presence of free iron on the stainless steel surface.

It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. The ASTM A passivation standard applies to the cleaning, passivation and testing of stainless steel parts. 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. It makes no a9670-5 regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.

At the end of astmm period, the surface shall be carefully rinsed and dried with care taken not to disturb copper deposits if present. Determination of the suitability of this speci? This test shall not be applied to parts to be used in food processing. The cloth pad used shall be used for only one such test, being changed for each test so as to avoid risk of contamination.

These particles must be removed or they will appear as rust or stain spots.

It includes several alternative tests, with acceptance criteria, for confirmation of effectiveness of such treatments for stainless steel parts. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment aatm to particular grades of stainless steel.

The presence of exogenous surface contamination, including dirt, grease, free iron from contact with steel tooling, and so forth, may interfere with the formation of the passive?

This test is not recommended for detection of free 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.

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. 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.
