Verwendung einer Nickel-Chrom-Molybdän-Legierung

摘要

The invention relates to a kneadable, homogeneous, austenitic nickel alloy having a high corrosion resistance in relation to aggressive media under both oxidating and reducing conditions, excellent resistance to local corrosion in acid chloride-containing media and high structural stability following thermal stress. Said alloy consists of the following ( % by mass): chromium 20.0 to 23.0 %, molybdenum 18.5 to 21.0 %, iron max. 1.5 %, manganese max. 0.5 %, silicon max. 0.10 %, cobalt max. 0.3 %, wolfram max. 0.3 %, copper max. 0.3 %, aluminium 0.1 to 0.3 %, magnesium 0.001 to 0.015 %, calcium 0.001 to 0.010 %, carbon max. 0.01 %, nitrogen 0.05 to 0.15 %, vanadium 0.1 to 0.3 %, with the rest consisting of nickel and other impurities resulting from the melting process. Said alloy is a suitable material for objects resistant to chemical attack and as super-alloyed solder for other nickel-based materials.
