UNS S31500 (1.4424, X2CrNiMoSi18-5-3) is a super duplex stainless steel material, which is a kind of austenitic-ferritic material. It has very good performance in the environment required high resistance and high stress like oil refineries, Chemical industry and Super alloys or high-performance alloys are of three types that include iron-based, cobalt-based, and nickel-based alloys. These alloys are of different shapes and they possess good oxidation and creep resistance. Superalloys can function under high mechanical stress and high temperatures and also in places that require high surface stability. Superalloys can be strengthened by precipitation hardening, solid-solution hardening, and work hardening methods.
