Hastelloy buttweld fittings—usually employing grades such as C22, C276, or X—have high nickel content (about 56%), molybdenum (13–17%), chromium (15–22%), and iron, with small traces like tungsten and cobalt. The compositions provide superior resistance to pitting, stress-corrosion cracking, and crevice corrosion. Tensile strength of up to 800 MPa, yield strength around 350–400 MPa, and good elongation are provided by the alloy. Hastelloy fittings have mechanical strength over a broad temperature range and are particularly dependable in acidic, high-temperature, and contaminated environments.
