These tests include the following practices: It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.

Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance.

An example would be application of Practice C on some lesser-alloyed martensitic or ferritic stainless steels. 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.

Such treatments may include externally applying an electrical potential on the stainless steel parts, as in the case of electropolishing. The cleaning of these contaminants from the stainless steel surface will facilitate the spontaneous passivation by allowing the oxygen uniform access to the surface. All samples must pass the speci?
