E10018-D2 is a high quality electrode used
for joining high tensile steels and manganese
molybdenum steels. 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. E10018-D2 is specifically designed
for applications requiring at least 100 ksi
tensile strength, good ductility and crack
resistance.

Applications
• Manganese-Moly castings
• Alloy Forgings
• Structure and pressure vessels
