ESAB® AtomArc® E8018-C2 H4R 8018-N Low Alloy Steel Electrode with 3/32" Dia develops an excellent weld properties and is used to fabricate components where low temperature notch toughness value is needed. The improved coating offers an extra degree of reliability, especially for electrode. Moisture resistant 3.5% nickel is ideal for 2 - 4% nickel steels and the flux coatings are designed to effectively resist moisture pick-up in opened containers. Low hydrogen electrode comes in a 50 lb hermetically sealed container.
Features
Moisture resistant coatings are incorporated in all AtomArc® electrodes
The flux coatings are manufactured to effectively resist moisture pick up in opened containers
The improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
Specifications
AWS A5.5
ASME SFA 5.5
Applications
Used to fabricate components where low temperature notch toughness values are required
Recommended for welding the 2% to 4% Ni steels
Caution
Preheat should be used on hardenable steels to prevent the formation of a hard heat-affected zone
Preheat may also be required in welding heavy sections
