Ferritic, austenitic and ferritic-austenitic duplex stainless steelsmay be subject to such an attack when they are ba at atemperature between about C and 1 C.
Bw comparison of the two pieces enables it to be establishedwhether or not the cracks observed on the corroded test piece are due to intergranular corrosion. Please download Chrome oso Firefox or view our browser tips.

For cast products, the radius of the mandrel shall be no more than twice the thickness ofthe test piece. Unless specified in the product standard, the method to be used, A, B or C, shall form the subject of anagreement between the interested parties. The test piece shall be bent to at least 90 over a mandrel with a radius sn exceeding the thickness ofthe test piece. The work of preparing International Standards is normallycarried out through ISO technical committees.
The test pieces are firstlyimmersed in the cold test solution following which the solution is brought to the boil, from which pointonwards the test duration commences.
Thefollowing examples are given as information. Each member bodyinterested in a subject for which a technical sio has beenestablished has the right to be represented on that committee. Corrosion test in media containing sulfuric acid. In sio case of the chemical preparation, it shall be necessary to ensure in advance that intergranularcorrosion does not occur due to the preparation.
NOTE When an evaluation is questionable a metallographic examination of a 3651-22 cross section of the test piecemay be used to detect the presence of intergranular corrosion and to measure the depth of penetration. NOTE Corrosion rates bw expected to increase if all the ferric sulfate is used up. It also specifies the purposes which may be assigned to the test.
