ASTM B564 Inconel 625 UNS N06625 Weld Neck Flanges WN RTJ ASME B16.5 API 6A
We are the manufacturer of ASTM B564 Inconel 625 UNS N06625 Weld Neck Flanges WN RTJ ASME B16.5 API 6A in China.
What is Inconel 625 ?
Alloy 625,Inconel 625 also known as UNS N06625 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.
Inconel 625, Alloy 625 is a low carbon (0.03%) nickel-chromium-molybdenum-niobium alloy which has excellent corrosion resistance to a wide range of corrosive media. Alloy 625 is normally supplied in annealed condition for wet corrosion applications and is TÜV-approved for pressure vessels in the temperature range from -196°C to 450°C. In annealed condition (grade 1) Alloy 625 is characterized by:
About the Inconel 625 Weld neck flange
Weld Neck Flanges made from ASTM B564 UNS N06625 are designed to be welded onto pipes and are frequently used in high-pressure and high-temperature applications. These flanges typically have a long tapered neck that is welded to the pipe, providing strength and resistance to stress.
