### **Product Data Sheet: Alloy PE11 / Nimonic PE11 Pipe (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 **pipe**, this material provides **good creep strength, excellent oxidation resistance, and reliable pressure containment** at temperatures up to 750°C (1380°F). Nimonic PE11 pipe is engineered for high-temperature, moderate-pressure applications where conventional stainless steels would fail. The pipe form maintains the alloy's characteristic high-temperature strength while providing reliable fluid and gas conveyance under thermal and mechanical stress conditions in demanding industrial environments. --- #### **1.
