Request QuoteWhat Are Monel 400 Bolts?
Monel 400 Bolts are precision-engineered fasteners made from a solid solution of nickel (63%) and copper (28-34%). The alloy is renowned for its outstanding resistance to seawater, hydrofluoric acid, sulfuric acid, and caustic environments. These bolts are non-magnetic, thermally stable, and highly resistant to stress corrosion cracking, pitting, and erosion. Ideal for high-temperature and high-pressure applications, Monel 400 bolts offer superior longevity compared to stainless steel or carbon steel fasteners.
