Nimonic 80A is a high-performance super alloy with exceptional strength and resistance to corrosion and heat. It was developed in the 1940s by the research team at the British company, Nimonic Alloys. Since then, it has become a crucial material in various industries such as aerospace, power generation, petrochemical, and marine engineering.
Applications of Nimonic 80A
Nimonic 80A‘s high-temperature strength, excellent creep resistance, and resistance to oxidation and corrosion make it ideal for applications in harsh environments. One of its primary uses is in gas turbine engines, where it is used for critical components such as turbine blades, nozzles, and combustion chambers.
The alloy’s superior mechanical properties also make it suitable for use in other high-stress applications such as aircraft exhaust systems, furnace equipment, and nuclear power plants.
Equivalent and Chemical Composition
The chemical composition of Nimonic 80A includes high amounts of nickel, chromium, and cobalt, along with small amounts of other elements such as iron, manganese, silicon, and aluminum. The alloy’s composition provides excellent resistance to corrosion, oxidation, and high-temperature creep.
In terms of equivalent materials, Nimonic 80A is similar to Inconel 718, but with higher tensile and yield strengths. Other alternatives include Haynes 188, Waspaloy, and Rene 41.
Mechanical Properties
Nimonic 80A is known for its excellent mechanical properties, including high strength, toughness, and ductility even at elevated temperatures. Its ultimate tensile strength ranges from 730 MPa to 1035 MPa, with a yield strength of 420 MPa to 550 MPa.
The alloy’s improved creep resistance allows it to withstand high temperatures up to 815°C for extended periods without deformation. Nimonic 80A also exhibits excellent fatigue resistance, making it ideal for high-stress applications.
Production Standard
Nimonic 80A is produced according to various international standards, including AMS 5766, BS HR1, and ASTM B637. The alloy is typically manufactured using vacuum induction melting (VIM) followed by electroslag refining (ESR) or vacuum arc remelting (VAR). This process ensures high purity and uniformity of the material, leading to consistent mechanical properties.
Round Bar, Plate, Sheet, Strip, Pipe, Wire Rod
Nimonic 80A is available in different forms including round bar, plate, sheet, strip, pipe, and wire rod. These forms vary in size, thickness, and diameter depending on the specific application.
The round bar is typically used for manufacturing components such as shafts and fittings, while the plate and sheet are used for fabrication of structural components. The strip is commonly used in high-temperature sealing applications, while the pipe is used in corrosive environments.
