A novel, nickel-base, high temperature alloy body preferably containing about 20% chromium, 6 to 7% aluminum to provide phase, 1.5 to 2.5% molybdenum, 3 to 4.5% tungsten, additional strengthening elements and oxidic yttrium in finely dispersed form. The alloy body has an elongated crystal structure and is characterized by high strength along with excellent hot corrosion and oxidation resistance.

Nickel-base alloys containing special and correlated percentages of chromium, iron, molybdenum, titanium, columbium, aluminum etc. (i) provide an attractive combination of strength, ductility, resistance to environmental media and other desirable characteristics, (ii) can be processed by cold working and age hardening to achieve yield strengths of 150,000 psi (1034 MPa) to 200,000 psi (1379 MPa) together with tensile elongations of 10% to 20%, (iii) are resistant to such corrosive media as hydrogen sulphide and acid chloride solutions, and to hydrogen embittlement, and (iv) are useful for, inter alia, petroleum production tubing and sulfur dioxide gas scrubber applications.

Corrosion resistant high-strength nickel-base alloy

A novel nickel-base high temperature alloy body preferably containing about 22% chromium, sufficient aluminum and titanium to provide a .gamma.' precipitate structure, additional strengthing elements and oxidic yttrium in finely dispersed form. The alloy body has an elongated crystal structure and is characterized by high strength along with excellent hot corrosion and oxidation resistance.
