CROMOTHERME-5L(MOD)
AWS: SFA
EN ISO CODE:
Cromotherme-5L(MOD) is a basic coated, low carbon, low hydrogen type electrode depositing a weld metal with 5% Cr-0.5% Mo, ideally suited for welding of creep resisting steels of similar composition where superior notch toughness required at sub-zero temperatures. Typical applications include welding of 5% Cr-0.5% Mo steels in oil refinery, chemical plant, and equipments. Specifically applicable wherever prolonged heat treatments are involved.
