Typically, Hastelloy Forged Fittings are composed of nickel-based alloys like Hastelloy C22, C276, or C2000, which contain trace amounts of iron, cobalt, and tungsten along with high concentrations of nickel (≈56–59%), molybdenum (13–17%), and chromium (15–22%). These fittings have an elongation of 45–60%, a yield strength of about 283 MPa, and a tensile strength of 690–760 MPa. Hastelloy is well-known for its remarkable resistance to pitting, crevice corrosion, and stress-corrosion cracking. It also retains its strength and toughness in extremely corrosive and hot conditions, which makes it perfect for demanding process conditions and vital piping systems.
