CCR-200 is a semi-basic super heavy coated hardfacing electrode producing a high carbon, high chromium alloy weld deposit. The deposit resists corrosion and oxidation even at elevated temperature. The weld metal has excellent resistance to high temperature abrasion. Typical applications include hardfacing of blast furnace bells, hoppers, mixer blades, coal handling equipments, coal mill exhauster fan blades, excavator blades, scrapers, earth moving parts, crushing mills, screw conveyors, ash handling pipes, etc.
1. Re-dry the electrodes at 250-300°C for one hour for best results.
2. Use low current, short arc and stringer beads.
