Practice A—Water Immersion Test Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance.
It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts. Precision and Bias 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.
The presence of exogenous surface contamination, including dirt, grease, free iron from contact with steel tooling, and so forth, may interfere with the formation of the passive? The cloth shall be in contact with the steel for an area of at least 20 square inches cm2. Materials and Preparation for Passivation Treatments 5. The formation of a dark blue color within 30 s denotes the presence a67-05 metallic iron.
Immersion bath a967-0 be controlled at a pH of 1. 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.
ASTM A Passivation Standards | Passivated Stainless Steel Parts
It is the responsibility of the user of this standard to satm appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Originally approved in These tests include the following practices: Current edition approved Sept. It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.
It is especially useful for large parts that have been uniformly cleaned but that are inconvenient for reasons of size of equipment or ease of handling of the part to place in the environments de?
The pad shall be maintained wet through the test period, 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. Attention shall be given to maintaining adequate volume, concentration, purity, and temperature control appropriate to the size and amount of stainless steel to be treated. This cycle shall be repeated a minimum of twelve times.
It includes recommendations and precautions for descaling, cleaning, and passivation of stainless steel parts.
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 SI units given in parentheses are for information only.
Practice B—High Humidity Test The ASTM A passivation standard applies to the cleaning, passivation and testing of stainless steel parts. The suitability of such passivation treatments for astj in 3 meeting the requirements of this speci? The number of samples tested from a lot subject to retest shall be twice the original speci? An example a697-05 a medium that serves to accelerate the formation of the passive? It makes no recommendations regarding the suitability of any grade, treatment, or acceptance criteria for any particular application or class of applications.
These ASTM-approved tests may include: Precision Machining Technology Show. Treatments in Axtm Acid Solutions 6.
Such treatments, also sometimes called passivation in common usage, are designated as post-cleaning treatments in this speci? The surface of stainless axtm that has been pickled is free of scale, free iron, and exogenous foreign matter, and does not require a separate treatment for passivation as de?
This standard does not purport to address all of the safety concerns, if any, associated with its use.
ASTM A967 Passivation Standard
A superscript epsilon e indicates an editorial change since the last revision or reapproval. It includes several alternative tests, with acceptance criteria, for con? Active view current version of standard.
This test is not recommended for detection of free iron on ferritic a9967-05 martensitic series stainless steels, because these steels will give a positive indication irrespective of the presence or absence of anodic surface contaminants. The test solution shall be mixed fresh on the day of the test. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
