Product Description

HBE9018

Accord to AWS E9018-B3

 

Outstanding welding electrode for higher strength piping, castings and forgings. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. Electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity.
