Inconel 625 is a nickel-based alloy known for its excellent corrosion resistance and high-temperature strength. It is commonly used in aerospace, chemical processing, and power generation industries. One of the most popular forms of Alloy 625 Slip On Flange. This article will discuss the composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance of Inconel 625 flanges.
What is Inconel 625 Flanges?
UNS N06625 BLRF Flanges are high-performance flanges made from a nickel-chromium alloy designed to be highly resistant to corrosion and oxidation in extreme temperatures. This makes alloy 625 flanges an ideal option for high-temperature applications where other types of metal would not perform as well, such as ocean water, chemicals, flue gas streams and more. They provide excellent strength and toughness even at cryogenic temperatures.
Alloy 625 Flanges Composition
Nickel Alloy 625 Weld Neck Flange comprise a combination of nickel, chromium, molybdenum, and niobium. The nickel content is typically between 58% and 71%. Chromium is present in a range of 20.0-23.0%, and molybdenum content falls within the 8.0-10.0% range. Niobium and tantalum are often added to improve corrosion resistance and mechanical properties.
