CORROSION RESISTANT HIGH STRENGTH NICKEL-BASE ALLOY

摘要

Nickel-base alloys containing special and correlated percentages of chromium, iron, molybdenum, titanium, niobium, 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 psl (1034 MPa) to 200,000 psl (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 embrittlement, and (iv) are useful for, inter alia, petroleum production tubing and sulfur dioxide gas scrubber applications.
