Ferritic, austenitic and ferritic-austenitic duplex stainless steels – Corrosion test in media containing sulfuric acid ISO This website is best viewed with browser 365-11 of up to Microsoft Internet Explorer oso or Firefox 3. This standard is identical to: It is very important during corrosion tests to operate according to the referenced standards and to check the test parameters in order to obtain reliable and repeatable results.

ISO is specifically for duplex and all austenitic stainless steels, and recommends ageing at two different temperatures:. ISO is the most rigorous in terms of defining test methods, and says which alloys should use which test methods as follows: 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. Corrosion test in nitric acid medium by measurement of loss in mass Huey test.


Ferric sulfate-sulfuric acid test. Learn more about the cookies we use and how to change your settings. SEP does not require ageing, although it might be required in a specification calling up this standard. Corrosion tests in artificial atmospheres – Salt spray tests: None of these are identical and cross substitution of results is not possible.

Essai de corrosion en milieu acide nitrique par mesurage de la perte de masse essai de Huey Title in German Austenitische rostfreie Staehle. Some suggested criteria for the listed alloys are shown in Table 2, below. There are other requirements in these standards over details that are not discussed in this document, and these should be followed, such as conducting bend tests.

Where no specific test is specified, Table 5 suggests the most appropriate alongside io second choice, if the first is declined. The test solutions and exposures for some common intergranular corrosion tests.

More suitable alternatives are offered in Table 5, below. The most convenient size is often a cylinder 10mm diameter by mm long, but other dimensions are possible to suit 36511 product forms.

Nitric acid test Huey test Spec. Make an Enquiry Notice: Moreover its know-how and its qualified personnel permit also to study and to perform “special” corrosion tests for any kind of materials. This document also points out which alloys the tests are intended for, and recommends the most appropriate test when none is specified. Suggested test lso for different corrosion resistant alloys.

ASTM G28 does not require samples to be heat 6351-1. Related international standards This standard is identical to: ASTM G28 was designed for nickel-based alloys, and a list of applicable alloys for methods A and B is in the standard.

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. Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys. These latter are mostly fitted to customer requirements and shall be evaluated on request. The latter is a German test, but it is often called up in European sio. Both of these tests should be followed by water quenching.

Acetic Acid Salt Spray.

Good material should have a corrosion rate substantially less than the threshold value. Worldwide Standards We can source any standard from anywhere in the world.


It can be seen that some alloys fall into two categories, and no guidelines are given for selecting the most appropriate. SEP also gives guidance on which of its methods apply to which alloys: You may experience issues 365-1 this site in Internet Explorer 9, 10 or 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.

Ido, a welded test-piece in the as-welded condition may be tested. Find Similar Items This product falls into the following categories.
