Electrodes for Low Temperature Service
NITHERME-2.5 (Mod)
AWS: SFA 5.5 E10018-G
EN ISO CODE:
* Low hydrogen electrode depositing 2.8%Ni and 0.3%Mo weld metal. * Pleasing operating characteristics. * Weld metal of radiographic quality
Ideally suited for welding grain refined steels and nickel steels for service temperatures o down to minus 50 C. Typical applications include storage tanks for liquefied gases like Ammonia, distillers in coke oven batteries, petrochemical industries, DMR 249B (AB2) steel, etc. Also suitable for welding heavy sections and highly restrained joints subjected to dynamic loading, impact and severe service conditions.
