INCOLOY 20 (UNS N08020) is a nickel-iron-chromium austenitic alloy specially developed for excellent resistance to sulfuric acid, chloride-induced corrosion, pitting, and stress-corrosion cracking.
Stabilized with columbium (Nb), Alloy 20 provides superior mechanical strength, excellent metallurgical stability, and outstanding performance in strong acids and corrosive chemical environments.
This alloy is widely used in chemical processing, pharmaceutical production, pickling equipment, heat exchangers, and other anti-corrosion applications.
Material is typically supplied in annealed condition with full EN 10204 3.1 MTC.
