In such cases, the acid corrosion test is applicable, but not the oxalic acid etch test.

If any cross-sectional dimension is less than 1 cm, a minimum length of 1 cm a262–10 be polished. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

The copper should be washed and degreased before use. Drying may be facilitated, if desired, by dipping the specimens in acetone after they are scrubbed.

E To date, no data have been published on the effect of sigma phase on corrosion of AISI in this test.

The chart below comes from the ASTM A standard for selection of the appropriate test by alloy type:. See Appendix X1 for information regarding test selection. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. NOTE 21—Measures should be taken to minimize bumping of the solution when glass cradles are used to support specimens. Therefore, the area etched should be kept as small as possible while at the same time meeting the requirements of desirable minimum area to be etched.

Sand blasting should not be used.

ASTM A Intergranular Corrosion Testing and Analysis

A262-1 to Active This link will always route to the current Active version of the standard. For example, many low-carbon and stabilized stainless steels e. The etch structure types used to classify the specimens are: Based on your materials, application, and requirements, the other 4 methods provide specific focuses.

The latter may be formed in molybdenum-bearing and in stabilized grades of austenitic stainless steels and may or may not be visible in the microstructure. NOTE 5—Other equivalent means of specimen support, such as glass hooks or a62-10, may also be used.

Over 5 mm 3? The inch-pound equivalents are in parentheses and may be approximate.

NOTE 14—If the multi-sample testing apparatus see Note 10 is asgm, a asym number of specimens may be tested in the large container provided. All stainless grades listed in the accompanying table may be evaluated in these combinations of screening and corrosion tests, except those specimens of molybdenum-bearing grades for exampleL,and Lwhich represent zstm intended for use in nitric acid environments. However, in the special case of surface carburization sometimes encountered, for instance, in tubing or castings when lubricants or binders containing carbonaceous materials are employed it may be possible by heavy grinding or machining to remove the carburized surface 6 The sole source of supply of the apparatus known to the committee at this time is Amphoteric alundum granules, Hengar Granules, from the Hengar Co.

It is also sometimes used a2262-10 check the effectiveness of stabilizing elements and of reductions in carbon content in preventing susceptibility to rapid intergranular attack.

Specimens containing welds should be cut so that no more than mm 1?
