Hastelloy C22 Screws

Hastelloy C22 screws are high-performance nickel-chromium-molybdenum alloy fasteners known for their exceptional resistance to both oxidizing and reducing corrosive media, including wet chlorine and mixed acid environments. This versatile alloy, designated as UNS N06022, is particularly effective at resisting pitting, crevice corrosion, and stress-corrosion cracking, making it a critical material in the most aggressive industrial settings. At Zeron Fasteners, we manufacture and supply premium quality Hastelloy C22 screws suitable for challenging applications across the chemical processing, pollution control, marine engineering, and pharmaceutical industries, ensuring structural integrity and longevity.
