The Incoloy 825 washers from Marsh Nickel Alloys are made from a nickel-iron-chromium alloy, enhanced with molybdenum, copper, and titanium. This unique blend provides outstanding resistance to both oxidizing and reducing environments. These washers boast a tensile strength of about 550 MPa and a yield strength of roughly 220 MPa, along with impressive ductility and impact resistance. After undergoing heat treatment for improved performance, they retain their structural integrity across a broad temperature range. These mechanical properties make the Incoloy 825 washers from Marsh Nickel Alloys perfect for use in harsh environments where strength and corrosion resistance are essential.
