The composition of Hastelloy C22 Nuts from Themba Nickel Alloys includes nickel (56–63%), molybdenum (12–14%), chromium (20–22%), and iron (2–7%), along with small amounts of tungsten and cobalt. This unique mix gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, whether in oxidizing or reducing environments. Plus, they boast impressive mechanical properties, with tensile strength between 480–690 MPa and yield strength from 205–310 MPa, along with high toughness, ductility, and fatigue resistance. This means they can be relied upon to perform well even under extreme temperatures, pressures, and chemical exposure.
