Product Code : E9018-B3
Brand Name : S. R. INDUSTRIES
Product Description

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.
