Electrodes for Creep Resisting Steels
CROMOTHERME-23
AWS: SFA 5.5 E9015-B23
EN ISO CODE:
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.
