Atom
Arc 10018
(AWS E10018-M)
- The manganese-nickel-molybdenum
composition of Atom Arc 10018 is used
mostly on thinner sections of quenched and tempered low
alloy steels where 100,000 psi tensile strength, along with good ductility and
toughness at temperatures
as low as -60°F, are required. This product is used primarily for military
applications.

Atom
Arc 10018MM
(AWS E10018-D2)
- This electrode, with its combination of
manganese and molybdenum, was originally
developed during World War II to repair and fabricate
manganese-molybdenum castings and armor plate. It is used to weld similar
composition low alloy steels, as well
as heat treatable steels comparable to hardenable steels.
