Just remember that these tests were devised for specific groups of alloys and should not be applied to all CRAs!

ASTM G28 lists alloys and specifies the test exposure 36512- each. Selection of a Test Method 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 3561-2. Essais enn corrosion en milieux contenant de l’acide sulfurique. The most convenient size is often a cylinder 10mm diameter by mm long, but other dimensions are possible to suit particular product forms.

ISO is the most rigorous in terms of defining test methods, and says which alloys should use which test methods as follows: SEP also gives guidance on which of its methods apply to which alloys: 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.

You may experience issues viewing this site in Internet Explorer 9, 10 or ASTM A was designed for austenitic stainless steels, specifically the series alloys. Contact us by Phone or Email to find out how we can help your industry.

Your basket is empty. Test Samples Samples may be rectangular em 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.

Determination of resistance to intergranular corrosion of stainless steels. Good material should have a corrosion rate substantially less than the threshold value. Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys. Click to learn more.

None of these are identical and cross substitution of results is not possible. 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. 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.

The latter is a German test, but it is often called up in European projects.

This test should be avoided for most CRAs, except in the circumstances described below, in section 4. ASTM G28 was designed for nickel-based alloys, and a list of applicable alloys for methods A and B is in the standard.

Aciers inoxydables ferritiques, austenitiques et austeno-ferritiques duplex. More suitable alternatives are offered in Table 5, below. The Huey test method C is only for molybdenum-free grades, such as L, as alloys with molybdenum show high rates of attack in this test.

For an alloy wn is not listed, look for an alloy with a similar composition to a listed alloy to determine the most suitable test.

Suggested test methods for different corrosion resistant alloys.

Take the smart route to manage medical device compliance. Please download Chrome or Firefox or view our dn tips. 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.

Corrosion test in media containing sulfuric acid. The exception to this is ASTM G28 method A, where rates for the onset of intergranular corrosion are described in reference 1. Determination de la resistance a la corrosion intergranulaire des aciers inoxydables. It does not say what to do about duplex or super austenitic alloys. Bend test criteria for several standards.
