This may be accomplished with the apparatus prescribed in 3.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. It may also be used to evaluate the effectiveness of stabilizing element additions Cb, Ti, etc. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. NOTE 7—Conversion factors to other commonly used units for corrosion rates are as follows: NOTE 5—It may be necessary to embed large specimens, such as from heavy bar stock, in copper shot on the bottom of the test?
Overall length shall be about mm 13 in. Report the corrosion rates as inches of penetration per month, calculated as follows: Each sample must be in a separate cradle so that the samples do not touch. Additional requirements are noted where necessary. See Sections 30 and The choices are listed in Table 1.

Proceed to Checkout Continue Shopping. Practice W is used as a screening test to avoid the necessity, for acceptable specimens, of more asfm testing required by Practices X, Y, and Z.
Gas evolved at the electrodes with entrained oxalic acid is poisonous and irritating. Your comments are invited either for revision of asrm standard or for additional standards and should be addressed to ASTM International Headquarters.
Application of these standard tests to the other ferritic stainless steels will be by speci? The bend test evaluations for the steel test specimens are presented.
As the voice of the U. Evaluation by Weight Loss It may also detect the presence z763 chi or sigma phase in these steels. This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides or nitrides in stabilized and unstabilized ferritic stainless steels. Subscription pricing is determined by: Determine the maximum angle of bend without causing cracks in such material by bending an untested specimen of the same con?
The solution volume-to-sample aztm ratio shall be maintained.

Referenced Documents purchase separately The documents aa763 below are referenced within the subject standard but are not provided as part of the standard. 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. This possibility must be considered in selecting the test method. However, if preliminary results are desired, the specimen can be removed at any time for weighing.
Fresh test solution would not be needed if the test were to run 48 or 72 h. The sample is then rinsed in water and dried. However, several specimens may be tested simultaneously. It is ideal to have all the specimens in one?
See Table 1 for a listing of alloys for which Practice W is appropriate. D Asstm loss measurements can be used to detect severely sensitized material, but they are not very sensitive for alloys noted with this superscript and may not detect slight or moderate sensitization. A small amount of copper shot eight to ten pieces on the bottom of the?
Need more than one copy? Times for steels not listed in Table 1 are subject to agreement between the supplier and the purchaser. Times for alloys not listed in Table 1 are a7633 to agreement between the supplier and the purchaser.
NOTE 6—Measures should be taken to minimize bumping of the solution when glass cradles are used to support specimens. Do not use sand- or grit-blasting. Combinations of alloys and test methods for which successful experience is available are shown in Table 1.
This standard is aa763 included in any packages. Supplementary requirements are noted as required. A — 93 The choices are listed in Table 1. However, in the special case of surface carburization sometimes encountered, for instance, in tubing when carbonaceous lubricants are employed it may be possible a73 heavy grinding or machining to remove the carburized layer completely.
All traces of oxide scale formed during heat treatment must be removed. If the sample is too thick, multiple specimens should be used. The alloys on which the test has been successfully applied are shown in Table asfm.
