Nickel Alloys Monel K500 Hex Bolts
Nickel Alloys Monel K500 Hex Bolts are high-performance threaded fasteners manufactured from the age-hardenable nickel-copper alloy Monel K500 (UNS N05500). Zeron Fasteners specializes in supplying and manufacturing these superior high-strength bolts that combine the excellent corrosion resistance characteristics of Monel 400 with greater strength and hardness, achieved through the addition of aluminum and titanium. The distinguishing feature of this product is its ability to remain non-magnetic down to -101°C and its resistance to spark formation, while resisting stress corrosion cracking in sour-gas environments. The primary application of these Monel K500 Hex Bolts is in demanding environments such as deep-well petroleum production (downhole tooling), marine pump shafts, valve components, doctor blades and scrapers in pulp and paper mills, and other high-stress, corrosive service.
