Product Code : E8018-B2
Brand Name : S. R. INDUSTRIES
Product Description

E8018-B2 welding electrode is for higher strength steels with tensile strengths greater than 80,000 pounds. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. This electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity.

Typical Applications : fabrication and maintenance of boilers and associated piping.
