This specification covers corrosion-resisting chromium and chromium- nickel steel welding rods for use with the atomic hydrogen and gas-tungsten-arc welding processes and bare electrodes for use with the submerged arc and gas metal-arc welding processes. These welding rods and electrodes include those alloy steels designated as corrosion- or heatresisting chromium and chromium-nickel steels@ in which chromium exceeds 4 per cent and nickel does not exceed 50 per cent. NOTE - No attempt has been made to classify all grades of filler metals within the limits of the above scope; only the more commonly used havebeen included.
