Hastelloy hydraulic fittings are mainly fabricated using nickel-molybdenum or nickel-chromium-molybdenum alloys like Hastelloy C-276 or C-22. The alloys have superior resistance to pitting, stress corrosion cracking, and oxidizing/reducing agents. Standard composition consists of about 57% nickel, 16% molybdenum, 15.5% chromium, 5% iron, and trace elements. Mechanically, these fittings have a tensile strength of about 690 MPa (100 ksi) and a yield strength of 283 MPa (41 ksi), with superior ductility and toughness. They retain good performance even at higher temperatures up to 1040°C, which makes them suitable for severe industrial processes.
