Abstract
Hard facing nickel-base alloy comprising 10 to 25% by weight of chromium, 3 to 15% by weight of molybdenum, 3 to 7% by weight of silicon, 1 to 2.5% by weight of carbon and 1 to 30% by weight of iron, the balance being substantially nickel. The alloy may also contain up to 0.4% by weight of boron, up to 15% by weight of cobalt, up to 4% by weight of tungsten, up to 3% by weight of tantalum or up to 2% by weight of tin, or two or more of these elements, if necessary. No porosity is likely to be produced in the hard facing layer of the alloy formed on a relatively small piece of base metal.
