Hastelloy® coated electrodes are nickel-based consumables that incorporate carefully controlled amounts of chromium, molybdenum, and iron, with certain grades also containing tungsten or cobalt. This unique alloy composition offers remarkable resistance to pitting, crevice corrosion, stress corrosion cracking, and high-temperature oxidation. The electrode coating promotes stable arc characteristics, smooth weld bead formation, and effortless slag removal. Typically, the weld deposits demonstrate high tensile strength, good ductility, and excellent impact toughness, ensuring mechanical integrity even under extreme thermal cycling and harsh service conditions.
Hastelloy® coated electrodes find extensive use in welding and repairing nickel alloy components that are subjected to highly corrosive and high-temperature environments. They are commonly applied in chemical reactors, pressure vessels, heat exchangers, piping systems, scrubbers, and pollution control equipment. Additionally, these electrodes are widely utilized in offshore, marine, aerospace, and power generation sectors. They are ideal for joining similar alloys, dissimilar metals, and for cladding applications, providing reliable, crack-resistant welds that ensure a long service life in critical operating conditions.
