CHARACTERISTICS :
Easy arc striking. Easy slag removal. Evenly rippled shining beads the weld deposit can withstand temperatures up to 1150°C in continuous service. Creep rupture strength at working temperatures is quite high. Use low current and short arc. This high carbon electrode is intended for service at elevated temperatures where creep resistance is of primary importance. Measurement of elongation at room temperatures is about 5% may be expected.

APPLICATIONS :
For welding reformer tubes (also called furnace tubes) made of HK 30 and HK 40 alloys used in fertiliser industries, oil refineries, petrochemical plants. Typical applications include hot dies and overlays on cast iron, salvaging pumps, valves and shafts working at high temperature.
