### **Product Data Sheet: Alloy PE11 / Nimonic PE11 Forgings (UNS N07113)** **Overview** **Alloy PE11** (commercially known as **Nimonic PE11**) is a precipitation-hardenable nickel-chromium 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 750°C (1380°F). Nimonic PE11 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.
