Avesta P12-R BASIC description: AVESTA P12-R basic is a nickel base electrode intended for 6Mo steels such as 254 SMO. It can also be used for welding nickel base alloys such as Inconel 625 and Incoloy 825. In chloride containing environments, the electrode offers particularly high resistance to pitting, crevice corrosion and stress corrosion cracking. As it has a fully austenitic structure, P12-R is slightly more sensitive to hot cracking than, for example, 316L. Consequently, low heat input and careful
control of the interpass temperature are essential.
