Abstract
A zirconium-based alloy for components in nuclear reactors with excellent resistance both to corrosion by water and water steam and to hydrogen absorption under operating conditions consists of 1.0-2.0 per cent by weight tin, 0.07-0.70 per cent by weight iron, 0.05-0.15 per cent by weight chromium, 0.16-0.40 per cent by weight nickel, 0,015-0.30, preferably 0,015-0.20 per cent by weight niobium, 0.002-0.05, preferably 0.015-0.05 per cent by weight silicon, 0.09-0.20, preferably 0.09-0.16 per cent by weight oxygen, the balance being zirconium and impurities, normally occurring in reactor grade sponge zirconium, of other kinds than the above-mentioned substances.
