U Bend Return , ASTM B366 Incoloy 800H 180 Deg. Elbow, Heat Exchanger
ASTM B366 is a specification for nickel-iron-chromium alloy fittings, including elbow butt weld fittings, made from Incoloy 800H material. Incoloy 800H is a high-temperature alloy that offers excellent resistance to oxidation, carburization, and other forms of high-temperature corrosion. These fittings are commonly used in applications such as chemical processing, heat treating, and power generation.
Common types of ASTM B366 Incoloy 800H elbow:
