This seems surprising Client specification calling for G48A Terst for 316L. What is the service and what is the level of Chloride ppm in service. What is the PREN requirement.

Please share the Snap shot of Client spec.

Dear Sir,

For SS316L material, we performed the Pitting Corrosion Test ASTM G48 Method A in accordance with the client's specifications and acceptance criteria, and we followed ISO 17781 standards in accordance with the client's standard reference.


We failed the test, and the weight reduction ranged from 50 to 500 g. It should be 1g according to the standard.


Can somebody advise or explain why this test failed?
