Zusammenfassung:A nickel-base alloy containing principally chromium molybdenum and tungsten is disclosed. The alloy is especially resistant to corrosion in a variety of corrosive media including oxidizing acids and reducing acids; furthermore, the alloy is not subject to localized corrosive attack, known as the "pitting" test. The alloy nominally contains 22% chromium, 13% molybdenum, 3% tungsten, 3% iron and the balance nickel plus small amounts of adventitious elements and impurities. Molybdenum and tungsten must be present in a ratio of about 4 to 1 respectively for optimum benefits of the invention.
