ISO is specifically for duplex and all ios stainless steels, and recommends ageing at two different temperatures: Where a bend test is required, the sample must be bent over a mandrel of a diameter related to the specimen diameter, without any cracking, as determined by inspection under a low power microscope and a microsection iiso any suspicious areas.

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

Make an Enquiry Notice: Test Samples 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. Determination of resistance to intergranular corrosion of stainless steels.

Corrosion test in media containing sulfuric acid Status: 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.

These tests were introduced when the carbon content in CRAs typically hit 0. Determination de la resistance a la corrosion intergranulaire des aciers inoxydables.

When a test has been selected, follow the detailed directions in ej standard for making up the test solution, the preparation of test samples and the finish to be used. Corrosion test in nitric acid medium by measurement of loss in mass Huey test.

Good material should have a corrosion rate substantially less than the threshold value.

Intergranular Corrosion Tests for CRAs

Take the smart route to manage medical device compliance. Just remember that these tests were devised for specific groups of alloys and should not be applied to all CRAs! Contact us by Phone or Email to find out how we eb help your industry. This means that carbide formation during welding is highly unlikely, and modern CRAs should easily pass one of these tests. Your basket is empty.


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. You may find similar items within these categories by selecting from the choices below:.

Accept and continue Een more about the cookies we use and how to change your settings. ASTM G28 method B is a more aggressive test than method A and is intended for more corrosion resistant alloys, as listed 351-2 the document.

SEP method 3 is a special environment only suitable for the Ni-Mo alloys, as described below, in section 4. There are a number of recognised tests when it comes to the intergranular corrosion testing of corrosion resistant alloys CRA.

The most convenient size is often a cylinder 10mm diameter by isso long, but other dimensions are possible to suit particular product forms. SEP also gives guidance on which of its methods apply to which alloys: Essais de corrosion en milieux contenant de l’acide sulfurique.

Table 1 below shows the various methods for four common standards: ASTM G28 lists alloys and specifies the test exposure for each.
