P31 is a medium-coated rutile electrode suitable for shipbuilding and structural steels as well as general-purpose fabrication in mild and medium carbon steels. It has particularly good operability in both downhand and positional welding. The coating of the electrode is of higher basicity than most other rutile types and provides weld deposits of high metallurgical, Grade 3 quality.
