If you feel that your comments aastm not received a fair hearing you should make your views known asstm the ASTM Committee on Standards, at the address shown below. Stainless Steel Passivation and More 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.
Practice B—High Humidity Test 9a67 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. These tests include the following practices: This standard does not purport to address all of the safety concerns, if any, associated with its use.
The parts shall then be thoroughly dried. Immersion bath to be controlled at a pH of 1. These particles must be removed or they will appear as rust or stain spots.
These ASTM-approved tests may include: The effectiveness of a particular treatment for a particular grade of stainless steel in a particular application is demonstrated by meeting the speci?

This cycle shall be repeated a minimum of twelve times. The SI units given in parentheses are for information only. 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?

NOTE 2—Some of the tests may produce positive indications not associated with the presence of free iron on the stainless steel surface. It is recommended for detection of free iron on austenitic and series stainless steels.
The surface of stainless steel resulting from these treatments is free of scale, free iron, and exogenous foreign matter, and does not require a separate treatment for passivation as de?
