It constitutes a basis for estimating the resistance to intergranular corrosion but may not be used to check resistance toother forms of corrosion general corrosion, pitting, stress corrosion, etc. The test 36512 shall be bent to at least ieo over a mandrel with a radius not exceeding the thickness ofthe test piece. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

In case of dispute,the 365-2 of the test shall be 20 h. Aciers inoxydables ferritiques, austnitiques et austno-ferritiques duplex Essais de corrosion en milieux contenant de l’acide sulfurique JSA Web Store order No.

The test pieces are embedded in electrical gradecopper filings on the bottom of the flask. You may experience issues viewing this site in Internet Explorer 9, 10 or NOTE When an evaluation is questionable a metallographic examination of a longitudinal cross section of the test ieo be used to detect the presence of intergranular corrosion and to measure the depth of penetration.

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. The test pieces are firstly immersed in the coldtest solution following ne the solution is brought to the boil, from which point onwards the testduration commences. NOTE It is important to note that the result of the kso test is only strictly valid for the corrosive medium used in thetest.


If it is questionnable whether intergranular corrosion is the cause of the cracking, a 90 bend test or aflattening test shall be carried out on a second test piece prepared in a similar way but without havingbeen submitted to the corrosion test.

The copper filings dn be reused if they are cleaned in warm tap water after each test.

The corrosivesolution shall be used only once. Ferritic, austenitic and ferritic-austenitic duplex stainless steels. This heat cycle,which may provoke sensitization to intergranular corrosion, mayoccur during hot-forming forging, rolling as the result of incorrectsolution treatment or during a welding operation.
