D&H 430 is a heavy rutile type electrode depositing a 17Cr weld metal. The weld metal displays good resistance to corrosion and heat. Ideally suited for surfacing of straight chromium steels and similar materials.
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.
