Can we use A182 F316L for Ball of API 6A API 3000 ball valve??

[samnoor]

We are manufacturer of API 6A ball valves. We used SS316 as per client request for making ball without any coating. But now in the line ball wash easily by sour gas flow. They need a document to show SS316 is not suitable for this pressure of ball valves. Any body have information and document about this point.

Thanks,
Sam

What sort of question is this: the client is asking the supplier for justification that the material, which the client requested, is not fit for the application? The client will have the necessary information in the failure analysis and root cause analysis that they should have performed after the failure.
