Stainless steel surface coatings has also influenced its use in commercial kitchens and food processing plants. Stainless steels do not suffer uniform corrosion, like carbon steel, when exposed to wet environments. Unprotected carbon steel rusts readily when exposed to the combination of air and moisture. The resulting iron oxide surface layer (the rust) is porous and fragile. Since iron oxide occupies a larger volume than the original steel this layer expands and tends to flake and fall away exposing the underlying steel to further attack. In comparison, stainless steels contain sufficient chromium to undergo passivation, spontaneously forming a microscopically thin inert surface
Sharon Steel Corporation the Sharon Steel Hoop Corporation in 1933. Aided by improvement in business conditions, the Sharon Steel continued to expand its sales volume and to make further improvements in production facilities during the thirties. Equipment for the production of terne and tin coating was added, a new product under the trade name of “Galvanite” was produced, and other specialties were added to the company's line of products. New electric furnaces were installed at the Lowellville Works to make stainless steel ingots to be converted into stainless steel strip on the Sharon finishing mills. A great change came about in the company
