Intergranular Corrosion Tests for CRAs

ISO is specifically for duplex and all austenitic stainless steels, and recommends ageing at two different temperatures: Some suggested criteria for the listed alloys are shown in Table 2, below.

None of these are identical and cross substitution of results oso not possible. Essais de corrosion en milieux contenant de l’acide sulfurique Title in German Ermittlung der Bestaendigkeit nichtrostender Staehle gegen interkristalline Korrosion.

Alternatively, a welded test-piece in the as-welded condition may be tested. These tests were introduced when the carbon content in CRAs typically hit 0. Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys. The specifications for bend testing are shown in Table 4. You may experience issues viewing this site in Internet Explorer eh, 10 or ASTM G28 was designed for nickel-based alloys, and a list of applicable alloys for methods A and B is in the standard.

Suggested test methods for different corrosion resistant alloys. Table 1 below shows the various methods for four common standards: Where a bend test is required, the sample must be 36512 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 in any suspicious areas.

Search all products by. R Baboian, Corrosion Tests and Standards: Hence, it is normally only used for stainless steels intended for 36512 service, or another application involving nitric acid. This document also points out which alloys the tests are intended for, and recommends the most appropriate test when none is specified. The most convenient size is often a cylinder 10mm diameter by mm long, but other dimensions are possible to suit particular product forms.

The latter is a German test, but it is often called up in European projects. Just remember that these tests were devised for specific groups of alloys and should not be applied to all CRAs!

More suitable alternatives are offered in Table 5, below. Find Similar Items This product falls into the following categories. Worldwide Standards We can source any standard from anywhere in the world.

This document describes all three of these tests for four common standards, and describes the differences. The exception to this is ASTM G28 method A, where rates for the onset ido intergranular corrosion are described in reference 1. The faster, easier way to work with standards. 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.

Essais de corrosion en milieux contenant de l’acide sulfurique. ASTM A was designed for austenitic stainless steels, specifically the series alloys. There are a number of recognised tests when it comes to the intergranular corrosion testing of corrosion resistant alloys CRA. SEP also fn guidance on which of its methods apply to which alloys: This test should 36511-2 avoided for most CRAs, except in the circumstances described below, in section 4.

Why were these tests designed?
