Abstract (en)
[origin: EP0570072A2] The invention relates to a chromium-base alloy having a chromium content of more than 65% by weight, and the following composition: 0.005 to 5% by weight of one or more rare earth oxides and 0.1 to 32% by weight of one or more metals from the group comprising iron, nickel and cobalt, the remainder being chromium. In addition, the alloy can contain up to 30% by weight of one or more metals from the group comprising Al, Ti, Zr and Hf, up to 10% by weight of one or more metals from the group comprising V, Nb, Mo, Ta, W and Re, and also up to 1% by weight of C and/or N and/or B and/or Si. As compared with pure chromium, the alloy has a markedly improved oxidation resistance and improved corrosion resistance, in particular against vanadium pentoxide.
