Atom Arc 7018-C3L

Atom Arc 7018-C3L is a low hydrogen, iron powder electrode that
produces a low carbon 1% nickel weld metal deposit.

Features

Atom Arc 7018-C3L is a low hydrogen, iron powder electrode that
produces a low carbon 1% nickel weld metal deposit. Weldments made
with Atom Arc 7018-C3L provide better notch toughness and lower
hardness when compared to an E8018-C3 class electrode.
Atom Arc 7018-C3L is used for the fabrication of cold storage tanks.
