2 inch pipe flange Inconel 718 steel flange fitting 2.4668 flange
The most common reason for Inconel is because it is an alloy that, despite exposure to high temperatures, provides excellent performance when common alloys fail.
As an alloy with nickel as the primary alloying agent, this excellent property is why any manufacturer of Inconel flanges today recommends their use in corrosive environments. Meanwhile, Alloy 718 is a nickel-chromium-molybdenum alloy designed for use in the power industry, aerospace, chemically processed components, and hardware and marine industries due to its corrosion resistance, pressure resistance, and heat resistance. Alloy 718 / Werkstoff Nr. 2.4668 is a nickel-chromium-iron material also used in the nuclear industry to eliminate the risk of stress corrosion cracking in high-purity water containing chloride ions.
