Dear Anil Kumar,

Yes, you are correct ASTM A380 is only for pickling and passivation.

A380 describes only pickling & passivation procedures in detail I believe, not about painting. Please correct me if I am wrong.

Dear Experts

Do we need pickling and passivation of SS surfaces before painting them? Could you please suggest any specification relevant this requirement?

The parts are SS cast valves requiring painting.
