Okoye Nickel Alloys is a reliable manufacturer and supplier of Monel Bolts based in Kinshasa, Congo. They’re known for producing high-quality bolts that boast exceptional strength, corrosion resistance, and durability. These bolts are meticulously engineered to perform consistently in tough industrial, marine, and chemical settings. Okoye Nickel Alloys provides Monel Bolts in a variety of sizes, thread types, and specifications, all crafted to meet international quality standards. Their clientele spans industries like chemical processing, marine engineering, offshore oil and gas, desalination, and power generation, offering secure and long-lasting fastening solutions for critical applications.
Monel Bolts are mainly made from a nickel-copper alloy, typically consisting of 67% nickel and 33% copper, with trace amounts of iron, manganese, and carbon to boost mechanical strength and corrosion resistance. This unique blend gives them excellent resistance to seawater, alkalis, hydrofluoric acid, and other harsh substances. With a tensile strength of around 620 MPa, yield strength of 275 MPa, and an elongation of 35%, these bolts ensure outstanding mechanical stability. The alloy retains its toughness, ductility, and dimensional integrity even at high temperatures, while also resisting stress corrosion cracking and embrittlement.
