GM 439 welding wire has excellent resistance to oxidation in air and in sulphur-containing combustion gases. Its strength at high temperatures is enhanced by the addition of Ti and Nb.
It is suitable for joining similar parent metals in, for example the high temperature part of exhaust systems for the automotive industry. It is also suitable for overlay welding, where oxidation resistance is required.
