S125332-033 - Hobart E8018-C3 1% Nickel Low Alloy Stick Electrode 2.5mm

High-Strength Low-Alloy Welding Solution

The Hobart E8018-C3 H4 Stick Electrode is a premium low-alloy steel electrode designed for critical welding applications requiring superior tensile strength and impact toughness. Engineered with a nominal 1% Nickel content, this electrode is specifically formulated to deliver a tensile strength of 80,000 psi, making it an ideal choice for structural fabrication where standard E7018 electrodes may not meet the mechanical requirements. The addition of nickel not only enhances the strength of the weld deposit but also significantly improves notch toughness at sub-zero temperatures, providing reliable impact resistance down to -40°F.

This 2.5mm electrode features a specialized coating designed to resist moisture absorption, a critical factor in preventing hydrogen-induced cracking in high-strength steels. The "H4" designation indicates a very low diffusible hydrogen content (less than 4ml per 100g of weld metal), ensuring the integrity of welds in susceptible materials such as T-1, AR (Abrasion Resistant) steels, and other low-alloy structural grades. Packaged in a durable 10lb can, these electrodes are protected from the environment until ready for use, maintaining their performance characteristics even in challenging job site conditions.

Suitable for a wide range of industrial sectors, the Hobart E8018-C3 is frequently utilized in shipbuilding, petrochemical infrastructure, and heavy construction. Its ability to produce X-ray quality welds with excellent mechanical properties makes it a trusted consumable for fabricating storage tanks, piping systems, and offshore platforms exposed to harsh environments.
