### **Product Data Sheet: Alloy PE16 / Nimonic PE16 Pipe (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 **pipe**, this material provides **good creep strength, excellent oxidation resistance, and reliable pressure containment** at temperatures up to 700°C (1290°F). Nimonic PE16 pipe is engineered for high-temperature, moderate-pressure applications where conventional stainless steels would be inadequate. 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.
