Electrodes for Creep Resisting Steels

Cromotherme-1(H4R) is basic coated, low hydrogen, moisture resistance type electrode. Weld metal display remarkable strength and creep resistance at elevated temperatures up to 550°C. Electrode is used for welding creep resistant 0.5Cr - 0.5Mo and 1Cr - 0.5Mo steels. Typical applications include steam boiler construction, welding of steam and super-heater piping, power plants, oil refinery and chemical plants.

1. Use short arc and stringer bead.

2. Re-dry the electrodes at 250°C for one hour, if expose to atmosphere.
