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. Conducting the Tests 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.
Intergranular Corrosion Tests for CRAs
ISO is specifically for duplex and all austenitic 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 in any suspicious areas. There are a number of recognised tests when it comes to the intergranular corrosion testing of corrosion resistant is CRA.

Ferritic, austenitic and ferritic-austenitic duplex stainless steels. SEP method 3 is a special environment only suitable for the Ni-Mo jso, as described below, in section 4. Some suggested criteria for the listed alloys are shown in Table 2, below. 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.
