Inconel 625 is a high-performance nickel-chromium-molybdenum alloy renowned for its exceptional corrosion resistance, high strength, and durability, even in extreme environments. Inconel 625 fasteners are a crucial component of this alloy's application in various industries, including aerospace, chemical processing, marine engineering, and oil and gas.
Chemical Composition: Inconel 625 is composed of nickel (58%), chromium (20-23%), molybdenum (8-10%), niobium (3.15-4.15%), iron (5%), and traces of other elements such as manganese, titanium, aluminum, and cobalt. This unique combination of elements imparts remarkable properties to the alloy, making it suitable for challenging conditions.
Corrosion Resistance: One of the standout features of Inconel 625 fasteners is their outstanding corrosion resistance. They exhibit excellent resistance to a wide range of corrosive media, including acids, alkalis, and seawater. This makes them ideal for applications in aggressive environments where other materials might succumb to corrosion.
