N06075

Haynes 75, also known as N06075, is a nickel-chromium alloy developed for applications requiring reliable performance at elevated temperatures. With a high nickel content and approximately 20% chromium, the alloy provides a combination of high-temperature strength, oxidation resistance, and good fabrication characteristics.

Haynes 75 can maintain its mechanical properties and resist creep at temperatures of approximately 800–850°C, making it suitable for components exposed to prolonged high-temperature service. The alloy also offers good resistance to scaling and oxidation in air, while its cold-forming and welding characteristics make it practical for different fabrication processes.

Key Features of Haynes 75

Excellent High-Temperature Performance

Haynes 75 is designed for elevated-temperature applications where mechanical stability is important. It can maintain its properties and resist creep at temperatures up to approximately 800–850°C, making it suitable for high-temperature components and equipment.

Its high-temperature capability allows manufacturers to use the alloy in applications where conventional stainless steels may not provide the required combination of strength and temperature resistance.

Good Oxidation Resistance

With approximately 20% chromium, Haynes 75 provides good resistance to oxidation and scaling when exposed to air at elevated working temperatures.

This characteristic is particularly useful for components operating in furnaces, heat-treatment equipment, gas turbine environments, and other high-temperature applications where surface oxidation can affect service life.

Good Manufacturability

High-temperature alloys need to provide not only service performance but also practical fabrication characteristics. Haynes 75 offers good cold-forming and welding performance, allowing it to be processed into different product forms and fabricated into components according to project requirements.

This balance between high-temperature performance and manufacturability makes N06075 suitable for applications involving forming, welding, and other conventional fabrication processes.
