发明名称 Corrosion-and-wear-resistant cobalt-base alloy
摘要 Disclosed is a cobalt-base alloy that has a valuable combination of both corrosion- and wear-resistant properties. The alloy nominally contains, in percent by weight, 25.5 chromium, 8.5 nickel, 3.0 iron, 5 molybdenum, 2 tungsten, 0.40 silicon, 0.75 manganese, 0.06 carbon, 0.08 nitrogen and the balance cobalt plus normal impurities normally found in alloys of this class. The alloy may also contain copper and certain "carbide formers" (i.e., columbium, tantalum, titanium, vanadium and the like) to tie up excess carbon and/or nitrogen that may be present.
