Practice F—Free Iron Test Not all of the following tests are suitable for all grades of stainless steel. Practice B—High Humidity Test Individual awtm single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
The SI units given in parentheses are for information only. It is recommended for detection of free iron on austenitic and series stainless steels. Precision and Bias Determination of the suitability of this speci? The ASTM A passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
ASTM A967 Passivation Standard
Practice D—Copper Sulfate Test Such treatments, also sometimes called passivation in common usage, are designated as post-cleaning treatments in this speci? A — 05 Standard Speci? The processor is not required to reveal the precise composition of proprietary chemical mixtures but shall maintain a unique identi? FebAnaheim, CA. This standard does not purport to address all of the safety concerns, if any, associated with its use.
It includes several alternative tests, with acceptance criteria, for con? Appendix X1 gives some nonmandatory information and provides some general guidelines regarding the selection satm passivation treatment appropriate to particular grades of stainless steel. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as atsm of the standard. The effectiveness of a particular treatment for a particular grade of stainless steel in a particular application is demonstrated by meeting the speci?
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. Rinsing can be accomplished by a combination of stagnant, countercurrent or spray rinses, or both, prior to? It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.
The pad shall be maintained wet through the test asgm, either by a method of retarding external evaporation, by the further addition of potable water, or by backing the pad with a sponge or similar water source. QQ-PC, but also includes a number of alternative passivation treatments.
Gain access to the technologies and people in aerospace and defense manufacturing. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. NOTE 1—The selection of medium and procedures for a96-705 neutralization depends of the chemistry of the passivation and on economic considerations.
Cleaning by mechanical methods or other chemical methods is recommended. The effectiveness of any passivation treatment is demonstrated by the parts meeting the speci?
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.
The number of samples tested from a lot subject to retest shall be twice the original speci? Active view current version of standard. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance. 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?
At the end of this period, the surface shall be carefully rinsed and dried with care taken not to disturb copper deposits if present. It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts.
ASTM A – 05 Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. These ASTM-approved tests may include:. The test solution shall be mixed fresh on the day of the test.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? These tests include the following practices: It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The cloth pad used shall be used for only one such test, being changed for each test so as to avoid risk of contamination. 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.
