Abstract (en)

[origin: WO2004024970A1] An iron-based alloy that contains the elements of cobalt, carbon, silicon, manganese, chromium, and optionally contains molybdenum, niobium, and tungsten, and optionally also minor amounts of one or more of aluminum, nickel, vanadium, nitrogen, sulfur and titanium. The combined amount of chrome and cobalt is at least 18 percent by weight of the total alloy, more preferably at least 34.5 percent by weight, and most preferably at least 36 percent by weight. The combined amount of chrome and cobalt is at most 41.5 percent by weight of the total alloy. The alloy is particularly suitable for use in mechanical parts which are thermally highly stressed and exposed to oxidizing and/or corroding effects, such as turbocharger nozzle rings.
