Flat Washers Overview
MW produced National USS high-strength stainless steel flat washers which are made of 17-7 precipitation hardened (PH) stainless steel and heat-treated to Rockwell C40-48 hardness. These flat washers provide the strength of heat treatment and the corrosion-resistance of stainless steel and can be used in environments where regular, well-plated steel, cannot survive.
