It may also detect the presence of chi or sigma phase in these steels. 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.
ASTM A Sensitization Testing of Ferritic Stainless Steel
Avoid excessive heat when dry-grinding. If the sample is too thick, multiple specimens should be used. It is the responsibility of the user of this standard to establish appropriate safety and adtm practices and determine the applicability of regulatory limitations prior to use.
In the annealed condition, they are not subject to intergranular corrosion.
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.

ASTM A763 – 15
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International A76. The ground-glass opening is somewhat over 38 mm 11? It has been reported that violent boiling resulting in acid spills can occur. Rinsing Prior to Examination 8. Specimens with unacceptable microstructures should be subjected to Practices X, Y, or Z to better determine their susceptibility to intergranular attack.
For any studies of IGA on Types,orthe indicated test methods are suggested. The ferric sulfate-sulfuric acid solution may also selectively attack titanium carbides and nitrides in stabilized steels. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Such treatment of test specimens is not permissible, except in s763 undertaken to demonstrate such surface effects. A7763 — 93 FIG. Current edition approved March a76, In the annealed condition, they are not subject to intergranular corrosion. Preparation of Test Specimens NOTE 6—Measures should be taken to minimize bumping of the solution when glass cradles are used to support specimens.
An equivalent area of copper shot or chips may be used. The choices are listed in Table 1. The test will not differentiate between intergranular attack resulting from carbides and that due to intermetallic phases.
Ordinarily, removal of more material than necessary will have little in? Four practices, including Practice W, X, Y, and Z, are used for determining susceptibility to intergranular attack in ferritic stainless steel.
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 will ensure detection of intergranular attack resulting from carburizing of one surface of sheet material during the? Preparation of Test Specimens aztm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Begin timing the test period when the solution reaches the boiling point. 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.
Warning—Protect the eyes and face by face shield and axtm rubber gloves and apron when handling acid. Your Alert Profile lists the documents that will be monitored. They should have three or four holes in them to increase circulation of the test solution around the specimen. Evaluation by Bend Test This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
