Electrodes for Creep Resisting Steels

Cromotherme-23 is a basic coated, low hydrogen type electrode depositing a weld metal of having less impurities i.e. S, P will improve the impact property at subzero temperatures. It is ideally suited for welding of creep resisting steels of similar composition. The weld deposit has excellent creep resistance at service temperatures up to 550°C. Typical applications include welding of P23 steels wherever prolonged heat treatment cycles are involved.

1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for one hour.

2. Use short arc, low current and stringer beads.
