ASTM B564 N06625 (2.4856) Nickel Alloy Blind And Weld Neck Flange
ASTM B564 N06625 Inconel 625 Nickel Alloy Blind And Weld Neck Flange
ASME SB564 UNS N06625, also recognized as Inconel 625, is a high-strength, corrosion-resistant nickel-based superalloy commonly used in aerospace, marine, and chemical sectors due to its ability to perform under extreme conditions.
Alloy 625 has enhanced corrosion protection due to its Chromium, Molybdenum, and Columbium content. It has excellent seawater corrosion performance. Chemical processing equipment relies on the corrosion performance over a wide range of environments. Applications requiring strength and oxidation resistance at temperatures up to 1 800 degrees. In aerospace applications include components of jet engine exhaust and thrust reversers.
