Product Overview of Hastelloy C22
UNS N06022 (Alloy C-22) is an advanced nickel-chromium-molybdenum-tungsten superalloy engineered to handle the world’s most severe industrial corrosion challenges. Featuring a balanced ratio of chromium, molybdenum, and tungsten, it outshines standard Ni-Cr-Mo alloys when dealing with mixed chemical streams containing wet chlorine, formic acid, acetic anhydride, and brine.
It serves as a primary material of construction in pharmaceuticals, pulp bleaching, and waste incineration where variable chemical states cause frequent corrosion failures.
Key Highlights of UNS N06022
✅ Broad Corrosion Spectrum: Outstanding resistance to both oxidizing and reducing chemical attack.
✅ Pitting Index Supremacy: Exceptional resistance to severe pitting, crevice corrosion, and stress corrosion cracking.
✅ Weldability Without Sensitization: Low carbon content prevents intergranular grain-boundary precipitation during joining.
✅ Halide Media Defense: Operates reliably in wet chlorine gas and ferric/cupric chloride solutions.
