E9018-B3 is a great electrode for welding
higher strength piping, castings and forgings.
The coating is specially formulated to resist
moisture pick-up under conditions of high heat
and humidity. E9018-B3 electrode offers
resistance to moisture reabsorption which
helps prevent hydrogen cracking and aids
in elimination of starting porosity.
Applications
• Chrome-Moly pipes
• Boiler work
