E9018M

< CLICK HERE for additional information on this alloy >

E9018-M is an electrode used for welding higher strength steels when tensile strength in excess of 90 ksi is required.  The coating on this electrode is specially formulated to resist moisture pick-up in conditions of high heat and humidity.  It’s resistance to moisture reabsorption also helps prevent hydrogen cracking and aids in elimination of starting porosity.

 

Typical Applications:   joining HY-90, HY-80, T-1 and other high tensile steels
