It is important to ensure that the concentration of acid does not become more concentrated and that an adequate number of boiling chips which are resistant to attack by the test solution are present.
A — 93 8. Combinations of alloys and test methods for which successful experience is available are shown in Table 1.
Fresh test solution would not be needed if the test were to run s763 or 72 h. Current edition approved March 1, For detecting susceptibility in environments known to cause intergranular attack due to these phases, use Practice X. Evaluation by Bend Test In the annealed condition, they are not subject to intergranular corrosion.
See Table 1 for a listing of alloys for which Practice W is appropriate. If the document is revised or amended, you will be notified by email.
ASTM A Sensitization Testing of Ferritic Stainless Steel
Begin timing the test period when s763 solution reaches the boiling point. Originally approved in We have no amendments or corrections for this standard. Individual reprints single or multiple copies of this standard may a673 obtained by contacting ASTM at the above address or at phonefaxor service astm.
Types,and are nonstabilized grades that are generally not used in the as-welded or sensitized condition in other than mildly corrosive environments. This possibility must be considered in selecting the test method. In no case shall the specimen be bent over a smaller radius or through a greater angle than that speci? C Preferred criterion, these criteria are the most sensitive for the particular combination of alloy and test. For very heavy sections, specimens a7633 be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing.
ASTM A763 – 15
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 copper should be washed and degreased before use. Gas evolved at the electrodes with entrained oxalic acid is poisonous and irritating.
The tests can be run without interruption. 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.
For any studies of IGA on Types,orthe indicated test methods are suggested. Shot is preferred for its ease of handling before and after the test. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Overall length shall be about mm 13 in. For specific safety precautionary statements, see 3. It may also detect the presence of chi or sigma phase in these steels.

Combinations of alloys and test methods for which successful experience is available are shown in Table 1. The number is limited only by the number of glass cradles that can be? NOTE 7—Conversion factors to other commonly used units for corrosion rates are as follows: This practices covers the detecting susceptibility to intergranular attack in ferritic stainless steel. Avoid excessive heat when dry-grinding.
Users of this standard z763 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.
Please first verify your email before subscribing to alerts. For detecting susceptibility to environments known to cause intergranular attack due to these x763 use Practice X.

NOTE 3—Loss of vapor results in concentration of the acid. It may also be used to evaluate the resistance of high purity or stabilized grades to sensitization to intergranular attack caused by welding or heat treatments.
See Table 1 for a listing of alloys for which Practice W is appropriate. Application of these standard tests to the other ferritic stainless steels will be by specific agreement between producer and user. As the voice of the U. 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.
