N08811 1.4876 elbow 45 degree

Model Number: PJJ-20 Brand Name: Bozhong Key Specifications/Special Features: IntroductionSuper alloys are also referred to as high performance alloys. They have good creep and oxidation resistance, anad are utilized where high surface stability is required. They also have an ability to function under high temperatures and mechanical stress. They can be strengthened by solid-solution hardening, work hardening, and precipitation hardening. They are divided into three groups such as iron-based, nickel-based, and cobalt-based alloys.Incoloy 800HT is a nickel-iron-chromium alloy, and also a modified version of alloy 800. It has high creep-rupture strength.Other DesignationsOther designations that are equivalent to Incoloy 800HT include:ASTM B407
