Abstract: Directed to ferritic nickel steel filler materials for gas-shielded arc-welding of cryogenic steels, such as the 9% nickel steel, which contain about 7% to about 13% nickel with specially controlled amounts of manganese and carbon and which produce welds having markedly improved impact resistance at cryogenic temperatures.
