Dear experts,

My query is:

I have weldments joining SS 304L # 17-4PH material. The weldments are subjected to heat treatment.

My customer is of the view that 17-4PH cannot be subjected to pickling and passivation after heat treatment. 

Can anyone provide technical literature as to why SS 17-4PH grade can't be subjected to pickling and passivation?

Thank you.
