The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface. Link to Active This link will always route to the current Active version of the standard. It asttm recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts.

These particles must be removed or they will appear as rust or stain spots. Such treatments may include externally applying an electrical potential on the stainless steel parts, as in the case of electropolishing. It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.

Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel. This standard does not purport to address all of the safety concerns, if any, associated with its use.

The ASTM A passivation standard applies to the cleaning, passivation and testing of stainless steel parts. These ASTM-approved tests may include:.

Precision and Bias 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. Cleaning by mechanical methods or other chemical methods is recommended.

ASTM A967 Passivation Standard

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. This test shall not be applied to parts to be used in food processing. The SI units given in parentheses are ast information only.
