### **Product Data Sheet: Alloy 105 / Nimonic 105 Pipe (UNS N07105)** **Overview** **Alloy 105** (commercially known as **Nimonic 105**) is a precipitation-hardenable nickel-chromium-cobalt superalloy specifically designed for high-temperature service. In the form of **pipe**, this material provides exceptional **creep strength, excellent oxidation resistance, and outstanding pressure containment capability** at temperatures up to 950°C (1740°F). Nimonic 105 pipe is engineered for high-temperature, high-pressure applications where conventional materials would fail. The pipe form maintains the alloy's characteristic high-temperature strength while providing reliable fluid and gas conveyance under extreme thermal and mechanical stress conditions. --- #### **1.
