Non-synthetic electrode for joining, repair and surfacing, to resist abrasion, corrosion, oxidation and high temperature service. Weld metal containing low carbon Cr-Mo-W-Co. Excellent resistance to heat, strength and toughness up to o 1000 C. Weld metal has good thermal shock resistance, hardness retention even at elevated temperatures and work hardening characteristics. Ideal for welding low carbon Ni-Cr-Mo alloys, clad side of low carbon Ni-Cr-Mo alloys and alloys of similar composition. Ideal for valves, valve seats, impellers, guide points, bushing, bearing, journals, hot working tools like hot shear blades, forging dies, trimming dies, piercing punches etc.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300-325 C for one hour.
2. Use short arc, stringer bead, and smallest possible size of electrode and minimum current to reduce the heat input.
