The composition of Hastelloy C276 Tubing from Themba Nickel Alloys includes nickel (57–63%), molybdenum (15–17%), iron (4–7%), and chromium (15–17%), along with small amounts of tungsten and cobalt. This unique mix gives the tubing remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, even in aggressive settings. It boasts excellent mechanical properties, with tensile strength ranging from 480–690 MPa and yield strength between 205–310 MPa, along with high toughness, ductility, and fatigue resistance. This ensures that the tubing performs reliably under extreme temperatures, pressures, and chemical exposure.
