The test methods in Table 1 were designed with specific alloys in mind, but the proliferation of new CRAs has meant that the selection of a suitable test method is difficult. ISO is 36511-1 most rigorous in terms of defining test methods, and says which alloys should use 351-1 test methods as follows: Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys.
ASTM G28 method B is a more aggressive test than method A and is intended for more corrosion resistant alloys, as listed in the document. Worldwide Standards We can source any standard from anywhere in the world.
Both of these tests should be followed by water quenching. ASTM G28 was designed for nickel-based alloys, and a list of applicable alloys for methods A and B is in the standard.
Hence, it is normally only used for stainless steels intended for nuclear service, or another application involving nitric acid. It has been used for the duplex stainless steel UNS Swhich has been used for nitric acid cooler tubes.

Also Slow Strain Rate Testing could be evaluated on request. Ferric sulfate-sulfuric acid test. The exception to this is ASTM G28 method A, where rates for the onset of intergranular corrosion are described in reference 1. Determination of resistance to intergranular corrosion of stainless steels – Ferritic, austenitic and ferritic-austenitic duplex stainless steels – Corrosion test in media containing sulfuric acid Pitting and Crevice Corrosion Tests according to: ISO is the most rigorous in terms of defining test methods, and says which alloys should use which test methods as follows:.
Moreover its know-how and its qualified personnel permit also to study and to perform “special” corrosion tests for any kind of materials.

Certified by ISO R Baboian, Corrosion Tests and Standards: Where a standard is included in a purchase specification, this must be followed, although it is advised that unsuitable tests, such as the Huey test for duplex and super austenitic stainless steels, are queried.

Acetic Acid Salt Spray.
Aciers austenitiques et austeno-ferritiques duplex. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. This document also points out which alloys the tests are intended for, and recommends the most appropriate test when none is specified. For an alloy that is not listed, look for an alloy with a similar composition to a listed alloy to determine the most suitable test. Conducting the Tests When a test has been selected, follow the detailed directions in that standard for making up the test solution, the preparation of test samples and the finish to be used.
The faster, easier way to work with standards. Bestimmung der Bestaendigkeit gegen interkristalline Korrosion.
Copper-copper sulfate-sulfuric acid test. As 15 hours is a difficult test period in practice, and is only a minimum, conducting the test for 20 hours overnight means that the two tests are equivalent. You may find similar items within these categories by selecting from the choices below:.
