Hello everybody, My query is as follows: I am working with incoloy 800 and am trying to make some corrosion tests according to ASTM G28, which uses a solution of ferric sulphate with sulfuric acid. The problem is that the sample was destroyed just six hours, including the test that is annealed solution. Someone would have experience in this matter. Thank you

Isoca5274 It depends. Incoloy 800 will fail and not suitable for dilute sulfuric acid. For ferric sulphate - depending on the concentration and temp, it depends on suitabiity. From your description, it could be dilute sulfuric acid for which Incoloy 800 is not suitable Hope this helps C.V.Srinivasan Nishi Engineers Pvt Ltd India Dec 18, 2008 E-mail: nishi@vsnl.com >Hello everybody, >My query is as follows: >I am working with incoloy 800 and am trying to make some >corrosion tests according to ASTM G28, which uses a solution >of ferric sulphate with sulfuric acid.

Thanks for your answer. Mi problem is that this test (ASTM G 28 A)is the especificated to this alloy. Moreover, my samples of incoloy 800, according this test, should last for 120 hours without intergranular corrosion. In my case the samples shows damage only at six hours. Best regards.
