Code and specification data. 7018 is a low hydrogen rod.

If you do not keep it in a rod oven after opening the can it will absorb water and cause cracks in high strength steel. Pinnacle alloys e9018 m is an outstanding welding electrode for welding higher strength steels with tensile strength in excess of 90 000 psi. The e7018 is a versatile welding rod frequently used for low and medium carbon steel welding. The coating is specially formulated to resist moisture pick up under conditions of high heat and humidity.

There are also military specifications such as the mil e or r types and federal specifications normally the qq r type and ams specifications. Excalibur 9018 b3 mr trade from lincoln electric is a low hydrogen stick electrode designed for all position welding of 2 25 chromium 1 molybdenum low alloy steels. Also referred to as a low hydrogen rod this electrode has a flux coating with a very low hydrogen content allowing a minimal amount of hydrogen into the weld puddle the molten weld beads are protected from contamination moisture and hydrogen in the atmosphere by the iron containing powder.
