Alloy/Inconel 625/UNS N06625 Flange is a nickel-chromium-molybdenum alloy that is used for its high strength, high toughness and excellent corrosion resistance. The strength of alloy 625,UNS N06625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition also provides a significant level of general corrosion resistance.

It is normally supplied in annealed condition for wet corrosion applications and is approved for pressure vessels in the temperature range from -196°C to 450°C. In annealed condition Alloy 625 is characterized by:

– good mechanical property

– Resistance to chlorine-induced stress corrosion cracking

– high resistance to mineral acids such as nitric, phosphoric, sulfuric, and hydrochloric acid

– good resistance to alkalis and organic acids

– exceptional resistance to pitting, crevice, erosion and intergranular corrosion
