Description:
P 83CR is a basic-coated, low hydrogen electrode which deposits a low carbon 1.25% Cr/ 0.5% Mo
weld metal. It is intended for welding creep resisting steels of similar composition, used in power
generation plant operating at temperatures up to 570°C, e.g. EN 13CrMo4-5, EN 10CrMo5-5, ASTM
A335 Gr P11-P12 etc. 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 150-200 °C is recommended.
Post-weld heat treat at 690°C.
