**Technical Datasheet: Alloy 75 (Haynes 75 / UNS N06075) Plate** **1. Introduction** Alloy 75 (commercially known as **Haynes 75** and standardized as **UNS N06075**) is a solid-solution strengthened nickel-chromium-tungsten alloy specifically engineered for extreme high-temperature applications. In **plate** form, this material offers exceptional mechanical strength, outstanding oxidation resistance, and excellent structural stability at temperatures up to 1200°C (2200°F). The plate product form is particularly suited for fabricating large structural components that must withstand severe thermal and mechanical stresses in aggressive environments. **2.
