Corrosion of B7 Bolts

Is it correct to use A193 B7 Bolts for stainless steels flanges e.g mono flanges, We used it in some cases and we discovered that it was corroding.

As BI states A193 B7 are commonly used in both CS and SS materials and if corroding I suspect may be due to particular environment and should be coated to protect e.g. hot dip galvanizing.
