Unibraze 9018-M (E9018-M) DESCRIPTION: UNIBRAZE 9018M is an outstanding welding electrode for welding higher strength steels with tensile strength in excess of 90,000 psi. The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity. The electrode offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. Definitely a preferred electrode with high operator appeal. APPLICATIONS: UNIBRAZE 9018M is used for joining HY-90, HY-80, T-1 and other high tensile steels. FEATURES: BENEFITS: ? Excellent arc characteristics ? Stable, easy to control arc ? Low spatter level ? Improves weld bead appearance, higher deposition ? Quick and easy slag removal ? Reduces clean-up time ? Low moisture reabsorption ? Prevents starting porosity ? Low smoke level ? Welder safety and comfort ? Low hydrogen, less than 4 ml/100 g ?
