These washers were available in the dimensions are DIN 125/127, ISO 7089/7090, ASME B18.22.1 even in some other dimensions also. The Nimonic 75 washers are available in different forms are Cold Formed, Hot Formed and Bar Stock Machined which are used based on the need. These washers are corrosion resistant also high temperature resistant with ultimate tensile strength. Due to its resistant it is widely used at the industrial machines where the temperature seems to be high. It should be free of mercury and radioactive contamination.
