Inconel flanges are high-performance pipe connectors made from nickel-chromium alloys, prized for their exceptional strength at extreme temperatures (cryogenic to 2200F/982C) and superior resistance to corrosion, oxidation, and stress-corrosion cracking in harsh environments like chemical processing, oil & gas, and aerospace. Key types include Inconel 600, 601, 625, and 718, offering various levels of resistance to oxidizing and non-oxidizing corrosive media, available in different styles (slip-on, weld neck, blind) and pressure classes for demanding applications.
Key Characteristics:
Material: Primarily Nickel (Ni), Chromium (Cr), Molybdenum (Mo), with Iron (Fe) and other elements.
Temperature Range: Excellent thermal stability, functioning from cryogenic lows to high heat (up to 2200F/982C).
Corrosion Resistance: High resistance to oxidation, pitting, and chloride stress-corrosion cracking, even in seawater.
Strength: High strength and stability under extreme pressure and temperature.
Common Types & Applications:
Inconel 600 (UNS N06600): Good resistance to oxidation, corrosion.
