ABSTRACT:
Directed to a corrosion resistant alloy particularly designed for use in power plant exhaust gas scrubbers which contains about 0.015% to about 0.025% carbon, not more than about 1% manganese, not more than about 0.3% silicon, about 19% to about 22% chromium, about 8.5% to about 9.5% molybdenum, about 30% to about 42% nickel, up to about 0.2% nitrogen, with the nickel and nitrogen contents being so related that at about 30% nickel, the nitrogen content is at least about 0.15%, while at a nickel content of at least about 40%, the nitrogen content does not exceed about 0.03%, the balance being essentially iron, with the iron content in the range of about 28% to about 40%.
