UNS N08825 elbow 45 90 180 degrees

Model Number: PJJ-26 Brand Name: Bozhong Key Specifications/Special Features: IntroductionSuper alloys have the ability to function at very high temperatures and mechanical stress, and also where high surface stability is required. They have good creep and oxidation resistance, and can be produced in a variety of shapes. They can be strengthened by solid-solution hardening, work hardening, and precipitation hardening.Super alloys consist of a number of elements in a variety of combinations to achieve the desired result. They are further classified into three groups such as cobalt-based, nickel-based, and iron-based alloys.Incoloy(r) alloy 825 is an austenitic nickel-iron-chromium alloy which is added with other alloying elements in order to improve its chemical corrosion resistant property.Other DesignationsOther designations that are equivalent to Incoloy(r) alloy 825 include:ASTM B163
