Okoye Nickel Alloys is a reputable manufacturer and supplier of Monel 400 Sheets and Plates based in Kinshasa, Congo. They’re known for delivering top-notch products that boast impressive corrosion resistance, strength, and durability. Each sheet and plate is meticulously engineered to ensure reliable performance, even in the toughest industrial, marine, and chemical settings. Okoye Nickel Alloys offers Monel 400 Sheets and Plates in a variety of sizes, thicknesses, and finishes, all crafted to meet international quality standards. Their products serve a range of industries, including chemical processing, marine engineering, offshore oil and gas, desalination, and power generation, providing robust and high-performance materials.
The Monel 400 Sheets and Plates are primarily made from a nickel-copper alloy, typically containing 66% nickel and 31–34% copper, with small amounts of iron and manganese added to boost mechanical strength and corrosion resistance. This alloy is particularly effective against seawater, alkalis, hydrofluoric acid, and other corrosive environments. With a tensile strength of around 620 MPa, a yield strength of 275 MPa, and an elongation of 35%, these sheets and plates ensure mechanical stability and toughness. They maintain their ductility and dimensional integrity even at elevated temperatures, resisting stress corrosion cracking and pitting.
