Incoloy Boiler Tubing is a nickel-iron-chromium alloy that includes varying amounts of molybdenum, copper, titanium, and aluminum, depending on the specific grade. The Incoloy 800 series typically features about 30–35% nickel, 19–23% chromium, with the remainder being iron. It boasts remarkable mechanical properties, such as tensile strength reaching up to 600 MPa, yield strength around 275–300 MPa, and impressive creep rupture strength at high temperatures. These alloys are designed to resist scaling, carburization, and oxidation, providing excellent structural stability even under prolonged thermal cycling—making them a reliable choice for boiler systems and high-temperature heat recovery applications.
