Products Description

Haynes282 alloy (UNS N07208) is a nickel-based superalloy, known for its exceptional high-temperature strength, excellent creep and fatigue resistance, and superior oxidation and corrosion resistance. The exceptional combination of mechanical properties, thermal stability, and corrosion resistance of Haynes 282 makes it a valuable material for applications where reliable performance under extreme conditions is essential. Its versatility and suitability for high-temperature environments have contributed to its widespread adoption in various industries.

Haynes 282 exhibits exceptionally high tensile and yield strengths, even at temperatures up to 1800°F (982°C). It maintains its strength and ductility at these elevated temperatures, making it well-suited for use in demanding high-temperature applications. The alloy also demonstrates excellent creep resistance, allowing it to withstand long-term exposure to high stresses and temperatures without significant deformation.

One of the key features of Haynes 282 is its superior oxidation and corrosion resistance. The formation of a protective oxide layer on the alloy's surface helps it withstand harsh, high-temperature environments, such as those encountered in gas turbine engines, industrial furnaces, and chemical processing equipment. This resistance to oxidation and corrosion makes Haynes 282 a preferred choice for applications where exposure to aggressive environments is a concern.

Haynes 282 finds widespread use in the aerospace, power generation, and chemical processing industries. In the aerospace sector, it is commonly employed in components like turbine blades, vanes, and combustion chambers, where its high-temperature strength, fatigue resistance, and oxidation resistance are critical. In power generation, the alloy is used in steam turbine parts and boiler equipment. It also sees application in the petrochemical industry, particularly in reactors, heat exchangers, and other process equipment operating at elevated temperatures.
