Sayam Nickel Alloys, headquartered in Hyderabad, is a trusted manufacturer and supplier of premium Hastelloy C-22 Fasteners. Known for precision, durability, and reliability, these fasteners are engineered to perform in highly corrosive environments, extreme temperatures, and demanding industrial conditions. Hastelloy C-22 Fasteners from Sayam Nickel Alloys provide long-term strength and operational stability, making them ideal for critical industrial applications. Using advanced manufacturing techniques and stringent quality control, every fastener meets international standards. Industries such as chemical processing, petrochemical, marine, and power generation rely on these fasteners for safe, efficient, and high-performance assembly in aggressive and high-temperature environments.
Hastelloy C-22 Fasteners are nickel-based alloys typically containing nickel (≈56%), chromium (≈20%), molybdenum (≈12%), iron (≈2–6%), and tungsten (≈3%). This composition provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in highly aggressive chemical environments. Mechanically, these fasteners exhibit high tensile and yield strength, excellent toughness, and good ductility. Their ability to maintain structural integrity under thermal cycling and corrosive exposure ensures reliable performance, making Hastelloy C-22 Fasteners suitable for demanding industrial applications requiring both mechanical strength and superior corrosion resistance.
