D&H 308H-17 is a stainless steel electrode depositing 19Cr-10Ni stainless steel weld metal with carbon in the range of 0.04-0.08. It works well with transformer and good re-striking characteristic. Better welder appeal including, easy slag detachability characteristics. On horizontal fillet welds, produce more of spray arc and a finer rippled weld bead and the bead shape is typically flat to concave. Weld metal possesses excellent crack resistance and displays good elevated temperature properties. Ideally suited for joining 18/8 stainless steels where the carbon content is in the range of 0.04-0.08 i.e. AISI 304H material.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for two hours.
2. Use short arc, stringer bead and low current.
3. Avoid build- up of heat during welding.
