### **Product Introduction: Nickelvac® 601 (UNS N06601) Nickel-Chromium-Iron Superalloy** **Nickelvac 601 (UNS N06601)** is a nickel-chromium-iron alloy renowned for its exceptional resistance to high-temperature oxidation and corrosion. This solid-solution strengthened superalloy demonstrates outstanding performance in temperatures up to 1250°C (2282°F), making it an ideal material for applications in aggressive thermal environments. The alloy's excellent high-temperature strength, combined with its resistance to carburization and sulfidation, has established it as a premier choice for industrial heating, thermal processing, and aerospace applications. The controlled addition of aluminum forms a protective, adherent oxide scale that provides remarkable resistance to cyclic oxidation, while the balanced chemical composition ensures structural stability and mechanical integrity under prolonged exposure to extreme temperatures. --- #### **1.
