Okoye Nickel Alloys is a reputable manufacturer and supplier of Monel 400 Coils based in Kinshasa, Congo. They’re known for delivering top-notch coils that boast impressive corrosion resistance, strength, and durability. These coils are meticulously engineered to perform reliably in tough industrial, marine, and chemical settings. Okoye Nickel Alloys provides Monel 400 Coils in a variety of thicknesses, widths, and lengths, all crafted to meet international quality standards. The company caters to sectors like chemical processing, marine engineering, offshore oil and gas, desalination, and power generation, supplying high-performance raw materials for essential applications.
Monel 400 Coils are mainly made from a nickel-copper alloy, typically containing 66% nickel and 31–34% copper, along with trace amounts of iron and manganese to boost mechanical strength and corrosion resistance. This unique composition offers outstanding resistance to seawater, alkalis, hydrofluoric acid, and other harsh substances. Monel 400 Coils have a tensile strength of around 620 MPa, a yield strength of 275 MPa, and an elongation of 35%, ensuring excellent mechanical stability. They maintain their toughness, ductility, and dimensional integrity even at high temperatures while resisting stress corrosion cracking and embrittlement.
