ASTM International takes no position respecting the validity of any patent awtm asserted in connection with any item mentioned in this 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 aatm free iron from the cold-worked surfaces.

The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface.

After removal of the cloth pad, the surface of the part shall be allowed to dry in air before inspection. 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 condition may be prevented by chemically treating the parts to remove the iron particles or other foreign particles, and then allowing the passive? Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection of passivation treatment appropriate to particular grades of stainless steel.
