GRACE M(7018 A1)
6013+
APPLICATIONS

Suitable for welding C-1/2 Mo low alloy and high tensile steels in high-temperature applications such as boilers, turbines, pressure piping, and oil refining. Electrodes should be dried at 250°C for 1-2 hours.

CHARACTERISTICS

An all positional, medium heavy coated, iron powder type, low hydrogen electrode depositing radiographic quality welds which are highly resistant to hydrogen induced cracking. Weld beads are smooth and spatter level is low. Works well on AC & DC.
