WELDING WIRE Russian patent published in 2003 - IPC

FIELD: welding materials, possibly restoration of large-size part of carbon steels operating in condition of cyclic thermomechanical loading, for example rolling rolls of mills for hot rolling by surfacing method. SUBSTANCE: alloy for electric arc surfacing of sublayer at restoration of rolling rolls contains the following ingredients, mas.%: carbon, 0.2 - 0.25; silicon, 0.4 - 0,7; manganese, 0.6 - 0.8; chrome, 0.8 - 1.0; nickel, 0.8 - 1.2; molybdenum, 0.6 - 0.8; vanadium, 0.2 -0.6; copper, 0.1 - 0.25; titanium, 0.01 - 0.02; sulfur, less than 0.05; phosphorus, less than 0.08; iron, the balance. EFFECT: increased useful life period of rolling rolls with sublayer surfaced at using welding wire of claimed content. 2 ex, 4 tbl
