Wstm of alloys and test methods for which successful experience is available are shown in Table. Current edition approved March 1, For detecting susceptibility to environments known to cause intergranular attack due to these phases use Practice X. Practice W is used as a screening test to avoid the necessity, for acceptable specimens, of more extensive testing required by Practices X, Y, and Z. As-welded specimens should be cut so that no more than 13 mm 1?

However, several specimens may be tested simultaneously. Application of these standard tests to the other ferritic stainless steels will be by specific agreement between producer and user.

Specimens with unacceptable microstructures should be subjected to Practices X, Y, or Z astmm better determine their susceptibility to intergranular attack. More ferric sulfate must be added if the total a7663 loss of all specimens exceeds 2 g. The sample atsm then rinsed in water and dried.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Evaluation by Microscopical Examination 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.

It may be applied to wrought products. If there is an appreciable change in the level, repeat the test with fresh solution and a reground specimen. Heavy specimens may require bending in a? Historical Version s – view previous versions of standard. This possibility must be considered in selecting the test method. The number is limited only by the number of glass cradles asfm can be?

Ordinarily, removal asym more material than necessary will have little in? The size of the cradles should be such that they can pass through the ground-glass joint of the Erlenmeyer? Link to Active This link will always route to the current Active version s763 the standard. The choices are listed in Table 1. NOTE 10—Cracks suspected as arising through poor ductility may be investigated by bending a similar specimen that was not exposed to the boiling test solution.

Determine the maximum angle of bend without causing cracks in such material by bending an untested specimen of the same con?

NOTE 7—Conversion factors to other commonly used units for corrosion rates are as follows: The test will not differentiate between intergranular attack resulting from carbides and that due to intermetallic phases. Do not use sand- or grit-blasting. Warning—Protect the eyes and face by face shield and use rubber gloves and apron when handling acid. It may also be used to evaluate the effectiveness of stabilizing element additions Cb, Ti, etc.

It may be applied to all wrought products and weld metal. Rinsing Prior to Examination 8. It is the responsibility of the user of this asstm to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

For very heavy sections, specimens should be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing. See Table 1 for a listing of alloys for asgm Practice W is appropriate. Four practices, including Practice W, X, Y, and Z, are used for determining susceptibility to intergranular attack in ferritic stainless steel.

The solution volume-to-sample area ratio shall be maintained. For detecting susceptibility in environments known to cause intergranular attack due to these phases, use Practice X. 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? This abstract is a brief summary of the referenced standard.
