Products >> A5.5, LOW ALLOY STEEL Covered Arc Welding Electrodes

 

E9018-B3

 

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.

 

Typical Applications:  chrome-moly pipes, boiler work
