Ninthore Overseas is one of the Leading Manufacturer And Exporter of Incoloy 925 Flanges, which are made by using finest quality material. Incoloy 925 Threaded Flanges (UNS N09925) can also be used for fasteners, and for pump shafts in marine environments. Molybdenum in Incoloy 925 Slip On Flanges aids resistance to pitting and crevice corrosion whilst Chromium offers resistance to oxidizing environments. Incoloy 925 Spectacle Blind Flanges has resistance to chloride ion stress – corrosion cracking. Because the Incoloy 925 Weld Neck Flanges offers excellent corrosion resistance in both oxidizing and reducing environments, the grade has proven useful in many “sour” applications in oil and natural gas applications.

Tooling and heavy duty machining equipment is used to reduce work-hardening of these Incoloy 925 Lap Joint Flanges. Meanwhile, these Incoloy 925 Blind Flanges are also being offered in different sizes and shapes to our customers. Incoloy 925 Socket Weld Flanges is produced by a vacuum re – melt process, but can be supplied using an air melt single consumable electrode practice if the material specification allows. The combination of nickel and chromium in Incoloy 925 Ring Joint Type Flanges renders protection in both oxidizing and reducing atmospheres.

High speed operations in Incoloy 925 Spacer Flanges such as grinding, milling or turning, are usually performed using water – based coolants. The molybdenum in Incoloy 925 Long Weld Neck Flanges aids resistance to pitting and crevice corrosion. The titanium and aluminum in Incoloy 925 Nippon Flanges additions cause a strengthening reaction during heat treatment.
