It is adtm to have all the specimens in one? All traces of oxide scale formed during heat treatment must be removed. Each sample must be in a separate cradle so that the samples do not touch. For very heavy sections, specimens should be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing.

Link to Active This link will always route to the current Active version of the standard. If the document is revised or amended, you will be notified by email. Preparation of Test Specimens For specific safety precautionary statements, see 3. This practices covers the detecting susceptibility to intergranular attack in ferritic stainless steel.

Warning—Protect the eyes and face by face shield and use rubber gloves and apron when handling acid. NOTE 2—Other equivalent means of specimen support such as glass hooks or stirrups may also be used. Already Subscribed to this document. Times longer than 24 h should be included in the test report.

It may also detect the presence of chi or sigma phase in these steels.

A number in parentheses indicates the year of last reapproval. NOTE 7—Conversion factors to other commonly used units for corrosion rates a76 as follows: This standard is also available to be included in Standards Subscriptions. Last previous edition approved in as A — 93 e1. The sample is then rinsed in water and dried. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Grind the cross section on wet or dry 80 or grit abrasive paper followed by successively?

It may be applied to all wrought products and weld metal. A superscript epsilon e indicates an editorial astk since the last revision or reapproval.

ASTM A Sensitization Testing of Ferritic Stainless Steel

More ferric sulfate must be added if the total weight loss of all specimens exceeds 2 g. For any studies of IGA on Types,orthe indicated test methods are suggested. This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides and nitrides in stabilized and unstabilized ferric atsm steels. A — 93 8. A copper cradle may also be used. Specimens with unacceptable microstructures should be subjected to Practices X, Y, or Z to better determine their susceptibility to intergranular attack.


This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides or nitrides in stabilized and unstabilized ferritic stainless steels. 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.

This abstract is a brief summary of the referenced standard. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. However, several specimens may be tested simultaneously. Need more than one copy? It may be applied to wrought products. It may be applied to wrought products and weld metal.

For specific safety precautionary statements, see 3. This standard is not included in any packages. 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?

The choices astk listed in Table 1. Fresh test solution would not be needed axtm the test were to run 48 or 72 h. A visual comparison between these specimens should assist in interpretation. Add the acid slowly to the water in the Erlenmeyer?

ASTM A763 – 15

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. Your Alert Profile aetm the documents that will be monitored. This possibility must be considered in selecting the test method. See Sections 30 and
