Inconel 625 Pipe Fittings (UNS N06625, WNR 2.4856)

Inconel 625 Pipe Fittings are high-performance components made from a nickel-chromium-molybdenum alloy (UNS N06625 / WNR 2.4856), engineered for applications demanding superior strength and exceptional corrosion resistance across a wide temperature range, from cryogenic to 1800°F (982°C). The unique solid solution effect from the addition of niobium (formerly columbium) and molybdenum gives the alloy its high tensile, creep, and rupture strength. These Inconel 625 fittings are vital in environments where resistance to pitting, crevice corrosion, and chloride-ion stress-corrosion cracking is essential. Zeron Fastners is a trusted name, offering a comprehensive range of these specialized fittings for critical industries. Key applications include aerospace ducting systems, chemical processing equipment, marine engineering (due to excellent seawater resistance), and nuclear reactor components. We supply high-quality nickel alloy pipe fittings manufactured to strict international standards.
