### **Product Introduction: Alloy 625 (Inconel 625) Plate // UNS N06625** **Alloy 625** is a nickel-chromium-molybdenum superalloy renowned for its exceptional combination of high strength and outstanding corrosion resistance across a wide temperature range. The alloy's superior performance is derived from the solid-solution strengthening effect of molybdenum and niobium (columbium) within its nickel-chromium matrix. This unique chemistry allows Alloy 625 to perform exceptionally well in both corrosive environments and high-temperature applications up to 1800°F (980°C), without the need for precipitation hardening treatments. Supplied as **Plate** and **Sheet**, this product form is engineered for critical applications requiring structural integrity, corrosion resistance, and high-temperature performance in demanding industrial environments. It is widely known by the trade name **Inconel® 625** and is standardized as **UNS N06625**. --- #### **1. Key Characteristics** * **Exceptional Corrosion Resistance:** Outstanding resistance to a broad spectrum of corrosive media, including pitting, crevice corrosion, and chloride-induced stress-corrosion cracking * **High Strength at Elevated Temperatures:** Excellent tensile, creep, and rupture strength maintained from cryogenic temperatures up to 1800°F (980°C) * **Superior Oxidation Resistance:** Provides excellent resistance to oxidation and scaling, ideal for high-temperature service * **Excellent Fabricability and Weldability:** Can be readily formed, machined, and welded using standard techniques without post-weld heat treatment to retain corrosion resistance --- #### **2.
