They should have three or four holes in them to increase circulation of the test solution around the specimen. Warning—Protect the eyes and use rubber gloves and apron for handling acid. Avoid excessive heat when dry-grinding.

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. The tests can be run without interruption. This abstract is a brief summary of the referenced standard.

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 sample is then rinsed in water and dried.

This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides and nitrides in stabilized and unstabilized ferric stainless steels. All other microscopical examinations are of the corroded surface under binocular examination see Section It is informational a736 and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

However, several specimens may be tested simultaneously. Additional requirements are noted where necessary. Preparation of Test Specimens The number is limited only by the number of glass cradles that can be? Evaluation by Weight Loss The bend test evaluations for the steel test specimens are presented. 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.

The alloys on which the test has been successfully applied are shown in Table 1. The ferric sulfate-sulfuric acid solution may also selectively attack titanium carbides and nitrides in stabilized steels. This may be accomplished with the apparatus prescribed in 3.

Asstm sample must be in a separate cradle so that the samples do not touch. However, if preliminary results are desired, the specimen can be removed at any time for weighing.
