Product Code : E12018-M
Product Description

E12018M is an outstanding electrode designed for use in applications which require weld joints with 110 ksi minimum tensile strength.  This electrode provides excellent puddle control with good wetting action and tie in.  The coating is specially formulated to resist moisture pick-up under conditions of high heat and humidity.  This electrode offers resistance to moisture re-absorption which helps prevent hydrogen cracking and aids in elimination of starting porosity.

Typical Applications: low alloys steels, castings, forgings, plate and pressure vessels
