316 Stainless Steel Flat Washers - Marine-Grade Corrosion Resistance

316 stainless steel flat washers offer superior corrosion resistance compared to 304 grade, thanks to the addition of molybdenum, which provides enhanced protection against chlorides, seawater, and acidic environments. They are the preferred choice for marine, offshore, chemical processing, and pharmaceutical fastener applications.
