**Inconel Buttweld Fittings** typically contain nickel (about 50–72%), chromium (14–23%), along with trace amounts of iron, molybdenum, copper, and carbon, depending on the specific grade. This unique composition grants them exceptional resistance to oxidation, pitting, and corrosion in both reducing and oxidizing environments, all while maintaining impressive mechanical strength. The fittings generally showcase tensile strengths between 550–860 MPa, yield strengths of 240–450 MPa, and elongation rates of 30–50%. They also boast excellent weldability, toughness, and long-term stability at high temperatures.
