See Table 1 for a listing of alloys for which Practice W is appropriate. It may be applied to all wrought products and weld metal. They should have three or four holes in them to increase circulation of the test solution around the specimen.
A aztm 93 8. The choices are listed in Table 1.
The alloys on which the test has been successfully applied adtm shown in Table 1. Active view current version of standard. In the annealed condition, they are not subject to intergranular corrosion. NOTE 2—Other equivalent means of specimen support such as glass hooks or stirrups may also be used. 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.
Please first verify your email before subscribing to alerts. Gas evolved at the electrodes with entrained oxalic acid is poisonous and irritating. This standard is not included in any packages. This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides or nitrides in stabilized and unstabilized ferritic stainless steels.
The choices are listed in Table 1. A76 the eyes and face by face shield and use rubber gloves and apron when handling acid.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The effect of galvanic coupling between copper and the test specimen may have importance 7.
Times longer than 24 h should be included in the test report. See Table 1 for a listing of alloys for which Practice W is appropriate. Need more than one copy? The ferric sulfate-sulfuric acid solution may also selectively attack titanium carbides and nitrides in stabilized steels.
This possibility must be considered in selecting the test method. Combinations of alloys and test methods for which successful experience is available are shown in Table 1.
ASTM A763 – 15
Subscription pricing is determined by: This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Application of these standard tests to the other ferritic stainless steels will be by specific agreement between producer and user. A superscript epsilon e indicates an editorial change since the last revision or reapproval. A visual comparison between these a73 should assist in interpretation. This possibility must be considered in selecting the test method.
It is generally completed by bringing the two ends together in the vise. Heavy specimens may require bending in a? As-welded specimens should be cut so that no more than 13 mm 1? A small amount of copper shot eight to ten pieces on the bottom of the?
It may be applied to wrought products and weld metal. Individual reprints single or multiple copies of this standard may ashm obtained by contacting ASTM at the above address or at phonefaxor service astm.
However, if preliminary results are desired, the specimen can be removed at any time for weighing.
ASTM A Sensitization Testing of Ferritic Stainless Steel
Combinations of alloys and test methods for which successful experience is available are shown in Table. NOTE 3—Loss of vapor results in concentration of the acid.
Please first log in with a verified email before subscribing to alerts. Grain dropping is usually an indication of intergranular attack, but the number of dropped grains per unit area that can be tolerated is subject to agreement between the supplier and the purchaser. Your Alert Profile lists the documents that will be monitored. Specimens with unacceptable microstructures should be subjected to Practices X, Y, or Z to better determine their susceptibility to intergranular attack.
