### **Product Data Sheet: Alloy PE16 / Nimonic PE16 Forgings (UNS N07115)** **Overview** **Alloy PE16** (commercially known as **Nimonic PE16**) is a precipitation-hardenable nickel-chromium-iron superalloy designed for high-temperature service. In the form of **forgings**, this material provides **good creep strength, excellent oxidation resistance, and reliable structural integrity** at temperatures up to 700°C (1290°F). Nimonic PE16 forgings are produced through controlled thermomechanical processes that refine the grain structure, enhance mechanical properties, and ensure metallurgical soundness. The forging process optimizes the alloy's inherent high-temperature capabilities, making it a reliable manufacturing route for components in moderately demanding high-temperature applications. --- #### **1.
