The flanges are made up of nickel (50–55%), chromium (17–21%), and iron (the balance), along with some niobium, molybdenum, titanium, and aluminum to boost their strength and corrosion resistance. They boast impressive mechanical properties, featuring a tensile strength of about 1,240 MPa and a yield strength of around 1,030 MPa, all while maintaining excellent toughness and creep resistance at high temperatures, up to 700°C. Plus, their outstanding fatigue and oxidation resistance means you can count on them in both high-pressure and high-temperature situations.
