Just remember that these tests were devised for specific groups of alloys and should not be applied to all CRAs! Find Similar Items This product falls into the following categories. ASTM G28 was designed for nickel-based alloys, and a list of applicable alloys for methods A and B is in the standard. 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.

Ferric sulfate-sulfuric acid test. You may find similar items within these categories by selecting from the choices below:. Is corrosion tests increased their importance both for the materials homologation and the failure analysis.

Samples may be rectangular or cylindrical to suit the test vessel, but where a bend test is required, it is suggested that the sample be a minimum of mm long.

SEP also gives guidance on which of its methods apply to which alloys: Please download Chrome or Firefox or view our browser tips. Bestimmung der Bestaendigkeit gegen interkristalline Korrosion. The faster, easier way to work with standards. Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys.

Determination of resistance to intergranular corrosion of stainless steels – Austenitic and ferritic – austenitic duplex stainless steels – Corrosion test in nitric acid medium by measurement of loss in mass Huey test UNIEN ISO ASTM G28 does not require samples to be heat treated.

Austenitic and ferritic-austenitic duplex stainless steels. Take the smart route to manage medical device compliance. Contact lso by Phone or Email to find out how we can help your industry. Good material should have a corrosion rate substantially less than the threshold value. Moreover its know-how and its qualified personnel permit also to study and to perform “special” corrosion tests for any kind of materials.

CORROSION TESTS

ASTM G28 lists alloys and specifies the test exposure for each. Also Slow Strain Rate Testing could be evaluated on request. Nitric acid test Huey test Spec.

Iwo method is applicable only to austenitic stainless steels supplied in the form of rolled or forged products and tubes and intended to be used in an oxydizing medium for example concentrated nitric acid. Hence, it is normally only used for stainless steels intended for nuclear service, or another application involving nitric acid.

3561-1 Conducting the Tests When a test has been selected, follow the detailed directions in that standard for making isp the test solution, the preparation of test samples and the finish to be used. ISO is the most rigorous in terms of defining test methods, and says which alloys should use which test methods as follows: More suitable alternatives are offered in Table 5, below.

Table 1 below shows the 365-11 methods for four common standards: Determination of resistance to intergranular corrosion of stainless steels. The specifications for bend testing are shown in Table 4. 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.

Both of these tests should be followed by water quenching. For alloys not listed in this standard, it will be necessary to carry out some tests on material in various conditions to determine the threshold.
