Abstract

Corrosion resistant alloys particularly for making pumps, valves, pipes, and other parts of chemical apparatus consist of 50-55 per cent of nickel, 20-30 per cent of chromium, 2-12 per cent of iron, less than 0,3 per cent of carbon, less than 1 per cent of manganese, up to 5 per cent of silicon, up to 6 per cent of molybdenum, up to 3 per cent of tungsten, and up to 7 per cent of copper. The alloy may be made by charging a furnace with low carbon steel and adding in succession chromium as ferro-chrome, copper and nickel partly as an alloy and partly as free nickel, and then the remaining ingredients while the bath is protected by a slag. The product is treated with a scavenger and poured into moulds.
