Stainless steel trim system to prevent galvanic corrosion of adjacent auto-body steel has been conceived by Applied Research Lab, U S Steel Corp; composite strip consisting of stainless steel with aluminum on one side would be processed conventionally to molding; aluminum would be on concave side of formed molding, and stainless on convex side, including visible surfaces and return surfaces of molding; after forming, return surfaces would be roll-or wipe-coated with paint or wax to provide electrical insulation at surfaces of trim and auto-body steel; road-exposure tests showed that stainless steel-aluminum composite performed better than uncoated stainless; when stainless steel-aluminum composite trim was coated on faying surfaces galvanic corrosion of automobile body was entirely prevented.
