Stainless Steel Flat Washers

National USS high strength stainless steel flat washers are made of 17-7 precipitation hardened (PH) stainless steel, heat treated to Rockwell C40-48 hardness. They provide the strength of heat treating and the corrosion resistance of a stainless steel and can be used in atmospheres where plain steel, no matter how well plated, cannot survive.
