Low Hydrogen Group
For welding carbon and low alloy steels that require 70,000 psi tensile strength
deposits. These low hydrogen electrodes can produce dense, x-ray quality welds
with notch toughness properties. The E7018 electrodes have "Fill-Freeze"
characteristics and the E7028 electrode has "Fast-Fill" characteristics.

Low Hydrogen, Low Alloy Steel Group
Made for welding low alloy steels that require specific mechanical or chemical
properties of one of these electrodes. Specifically for use in cryogenics, high
temperature applications, and for x-ray quality requirements. These electrodes have
Low Hydrogen "Fill-Freeze" operating characteristics similar to Jetweld LH-70.
