Abstract
A welding additive material substantially free of cobalt and carbide for deposit welding to obtain a welding deposit having high abrasion resistance, high corrosion resistance and high inter-granular corrosion resistance in the non-heat treated state, essentially consists of carbon up to a maximum of 0.15 percent, silicon in the range 3.00 to 10.00 percent, manganese in the range of 3.00 to 12.00 percent, chromium in the range of 22.00 to 30.00 percent and nickel in the range of 7.00 to 16.00 percent, each in percent by weight related to the proportion of the metallic components contained in the core wire and in the coating of a coated rod electrode or the filler of a filler wire of band filler. The remainder may be iron and unavoidable impurities.
