ABSTRACT:
The object of the present invention is to provide an alloy steel having excellent erosion resistance to molten zinc and used as a material for parts and members for molten zinc plating facilities, e.g. sink roll, coating roll, roll frame and snout. The alloy in the present invention consists essentially of, by weight percent, about 0.10 to 0.17 wt % of carbon, from about 0.30 to 2% of silicon, from about 0.30 to about 2% manganese, from about 10% to 20% nickel, from about 20% to about 35% chromium, from about 0.50% to about 5% molybdenum and from not less than about 0.40% to about 0.75% nitrogen, the balance consisting of substantially of Fe, and unavoidable impurities. Tungsten, from about 0.5% to about 5%, may also be added to enhance the strength of the alloy.
