Okoye Nickel Alloys is a reputable manufacturer and supplier of Monel 400 Bolts based in Kinshasa, Congo. They’re known for delivering top-notch fasteners that boast remarkable corrosion resistance, strength, and durability. These bolts are crafted with precision from high-grade Monel 400 alloy, ensuring they perform reliably in tough industrial, marine, and chemical settings. Okoye Nickel Alloys provides Monel 400 Bolts in a variety of sizes, thread types, and specifications, all made to comply with international standards. Their clientele spans industries like offshore oil and gas, marine engineering, chemical processing, desalination, and power generation, offering secure and long-lasting fastening solutions for critical applications.
Monel 400 Bolts are primarily made from a nickel-copper alloy, featuring around 66% nickel and 31–34% copper, along with trace amounts of iron and manganese to boost mechanical strength and corrosion resistance. This unique composition grants them excellent resistance to seawater, alkalis, hydrofluoric acid, and other corrosive substances. With a tensile strength of about 620 MPa, yield strength of 275 MPa, and an elongation of 35%, these bolts ensure outstanding toughness, ductility, and dimensional stability. They maintain their mechanical integrity even at elevated temperatures and resist stress corrosion cracking and pitting.
