### **Product Introduction: Alloy 625 (Inconel 625) Strip // UNS N06625** **Alloy 625** is a nickel-chromium-molybdenum superalloy known for its exceptional strength and corrosion resistance across extreme temperatures. The alloy achieves its properties through solid-solution strengthening from molybdenum and niobium in a nickel-chromium matrix, requiring no precipitation hardening. This chemistry provides outstanding performance in both corrosive environments and high-temperature applications up to 1800°F (980°C). Supplied as **strip**, this product form offers precise dimensional tolerances and superior surface finish for applications requiring thin, narrow coils with consistent properties. Commonly known as **Inconel® 625** and standardized as **UNS N06625**, this material is ideal for high-precision manufacturing. --- #### **1.
