E9018-B3 alloy welding electrode In accordance with AWS E9018-B3 Outstanding NOACH9018-B3 alloy welding electrode is for higher strength piping, castings and forgings.
Send InquiryE9018-B3 alloy welding electrode In accordance with AWS E9018-B3 Outstanding NOACH9018-B3 alloy welding electrode is 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.
