Elga P 84CR Electrodes

P 84CR is a basic-coated, low hydrogen electrode which deposits a low carbon 2.25% Cr/1.0% Mo weld metal. It is intended for welding creep resisting steels of similar composition, used in steam generation plant operating at temperatures up to 600°C, e.g. EN 10CrMo9-10, EN 11CrMo9-10, ASTM 335 Gr. P22, ASTM 217 Gr WC9. Also suitable for use in the chemical and petrochemical industries where resistance to hydrogen attack, corrosion from sulphur bearing crude oil and stress corrosion cracking in sour environments is required. Preheat and interpass temperature of 200-250°C is recommended. Post-weld heat treat at 690°C.
