### **Product Introduction: Alloy 625 (Inconel 625) Forgings // UNS N06625** **Alloy 625** is a nickel-chromium-molybdenum superalloy specifically engineered for applications demanding exceptional strength and superior corrosion resistance across extreme temperature ranges. Through the solid-solution strengthening provided by molybdenum and niobium within its nickel-chromium matrix, this alloy delivers outstanding performance in both corrosive environments and high-temperature applications up to 1800°F (980°C) without requiring precipitation hardening treatments. Supplied as **Forged Components**, these products benefit from the forging process that refines the grain structure, enhances mechanical properties, and improves structural integrity. Commonly known by the trade name **Inconel® 625** and standardized as **UNS N06625**, these forgings are essential for critical applications where reliability is paramount. --- #### **1.
