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 possibility must be considered in selecting the test method. The alloys on which the test has been successfully applied are shown in Table 1. As-welded specimens should be cut 7a63 that no more than 13 mm 1? A superscript epsilon e indicates an editorial change since the last revision or reapproval.

For specific safety precautionary statements, see 3. Rinsing Prior to Examination 8. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

NOTE 5—It may be necessary to embed large specimens, such as from heavy bar stock, in copper shot on the bottom a76 the test? Practice Wstm is used as a screening test to avoid the necessity, for acceptable specimens, of more extensive testing required by Practices X, Y, and Z.


NOTE 3—Loss of vapor results in concentration of the acid. Combinations of alloys and test methods for which successful experience is available are shown in Table 1. The choices are listed in Table 1.

You may delete a document from your Alert Ast, at any time. C Preferred criterion, these criteria are the most sensitive for the particular combination of alloy and test.

The choices are listed in Table 1. Subscription pricing is determined by: Report the corrosion rates as inches of penetration per month, calculated as follows: Need more than one copy? Standards Subsctiption may be the perfect solution. For detecting susceptibility in environments known to cause intergranular attack due to these phases, astmm Practice X. 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.

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. Specimens with unacceptable microstructures should be subjected to Practices X, Y, or Z to better determine their susceptibility to intergranular attack.

Application of these standard tests to the other ferritic stainless steels will be by speci? We have no amendments or corrections for this standard.

It is generally completed by bringing the two ends together in the vise. Ast has been reported that violent boiling resulting in acid spills can occur. Grind the cross section on wet or dry 80 or grit abrasive paper followed by successively?

For specific safety precautionary statements, see 3. However, several specimens may be tested simultaneously. In no case shall the specimen be bent over a smaller radius or through a greater angle than that speci? This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides and nitrides in stabilized and asttm ferric stainless a7633.

A visual comparison between these specimens should assist in interpretation.
