[MW:27644] Pickling and passivation of 17-4Ph Stainless steel

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.
