Inconel Buttweld Fittings are composed mainly of nickel (over 50%), chromium (14–23%), and small amounts of iron, molybdenum, niobium, titanium, and cobalt. This combination offers excellent oxidation and corrosion resistance at elevated temperatures. These fittings exhibit a tensile strength of approximately 930–1240 MPa and yield strength of 480–1035 MPa, depending on the grade. They also have high fatigue resistance, superior weldability, and excellent creep-rupture strength. Inconel’s unique metallurgical structure allows it to maintain mechanical stability and resist scaling even in harsh chemical and thermal environments.
