Lincoln Electric Excalibur 7018 MR 5/32 in 14
Lincoln Electric Excalibur 7018 MR stick electrodes are designed for stick welding on carbon and low-alloy steels. The 10 lb package contains electrodes with 5/32 in diameter and 14 in length. AWS classification E7018 H4R confirms low-hydrogen performance for critical joints.
Who should use these electrodes
Welders joining carbon steel to carbon steel, carbon steel to low-alloy steel, or low-alloy steel to low-alloy steel will find this classification suitable. The low-hydrogen coating helps meet stringent code requirements for structural work. Buyers who need a different diameter, length, or alloy type should look at other options.
The specification that decides fit
Minimum tensile strength is 70 ksi with as-welded results of 74 to 88 ksi. Minimum yield strength is 58 ksi with as-welded results of 62 to 74 ksi. If your procedure demands a higher or lower strength grade, this electrode will not match the specification.

Questions about this item
Will the Excalibur 7018 MR 5/32 in rods run on my older AC stick welder?
Yes, the E7018 H4R classification means they operate on AC or DC reverse polarity machines commonly found in older shops.
How can I verify the welds meet the 70 ksi tensile spec after welding?
Visual inspection for smooth bead profile and proper tie-in confirms technique; a bend test or lab tensile test validates the 74 to 88 ksi as-welded range.
Does the 10 lb package include any flux or storage container?
The box contains only the 5/32 in by 14 in mild steel electrodes; a separate rod oven or airtight canister is needed for low-hydrogen storage.
