The material combination is 316L Stainless steel and Electro galvanized steel which is used as liner plates in side of stainless steel door. The fasteners all are stainless steel and some place use welding also. The doors are using in water reclamation & treatment plant

EVERYTHING rusts in a treatment plant, even the stainless steel. I would make a small sample of the combination of metals and orientation, and put them in a neutral salt spray cabinet to see what happens.
