Inconel 925 Flanges

UNS N09925 Flange

We are Manufacturer, Supplier & Exporter of Incoloy Alloy 925 Flanges, which is annealed at 1010 Degree C (1850 Degree F) for 2 h followed by air cooling. Incoloy 925 Slip On Raised Flanges provides excellent resistance to stress-corrosion cracking, pitting and crevice corrosion in both oxidizing and reducing environments. Incoloy 925 Blind Raised Flanges combines the high strength of a precipitation-hardenable alloy with the excellent corrosion resistance of INCOLOY 825. Incoloy 925 Spectacle Blind Flanges has resistance to chloride ion stress – corrosion cracking. Because the Incoloy 925 Weld Neck Flanges have good corrosion resistance in both oxidizing and reducing environments, they have proven helpful in many "sour" applications in the oil and gas industries. Type Incoloy 925 Blind Flanges (BLRF) can be used in environments with high temperatures and mechanical stress, and also where high surface stability is required.

Incoloy 925 Plate Flanges have three groups of alloys such as cobalt-based, nickel-based, and iron-based alloys. Incoloy alloy 925 Slip On Flange (SORF) is a precipitation-hardenable nickel-iron-chromium alloy. Incoloy 925 Flat Face Flange it can be age-hardened by adding aluminum and titanium. Incoloy 925 Socket Weld Flanges are manufactured using a vacuum re-melt process, however they can also be supplied using an air melt single consumable electrode method if the material specification allows. The combination of nickel and chromium in Incoloy 925 Ring Joint Type Flanges provides protection in both oxidizing and reducing environments.
