D&H 444L is a special purpose electrode depositing12Cr - 4.6Ni - 0.5Mo weld metal, which has excellent resistance to corrosion, erosion, pitting and impact. Ideally suited for joining of similar composition materials, groove welding and surfacing applications. Typical applications include surfacing of high pressure valves, turbine blades, valve seats, repairs of runners, pulp and paper plant equipment, etc.
1. Ensure the electrodes are dry. Re-dry the electrodes at 200-250°C for one hour.
2. Use short arc and minimum heat input.
NOTE :D&H 444L-15 Conforming to AWS : E410NiMo-15 is also available.
