### **Product Introduction: Alloy 625 (Inconel 625) Bar // UNS N06625** **Alloy 625** is a nickel-chromium-molybdenum superalloy renowned for its exceptional strength and outstanding corrosion resistance across a wide temperature range. The key to its performance is the solid solution strengthening effect of molybdenum and niobium (columbium) on its nickel-chromium matrix. This eliminates the need for precipitation hardening treatments, allowing the alloy to retain its properties in both high-temperature and cryogenic environments. It is known by the common trade name **Inconel® 625** and is standardized as **UNS N06625**. We supply this superior material in various bar forms, including **Round Bars** and **Flat Bars**, to meet diverse industrial machining and fabrication needs. --- #### **1.
