Inconel 825 Buttweld Fittings

Inconel 825 is an alloy formulated of Nickel, Chromium and Iron with an extension of Copper, Molybdenum, and Titanium. The alloy was invented to contribute exceptional resistance to many corrosive environments and reducing environments that acquire sulphuric acid and phosphoric acid and sea water, sulphur containing flue gases, sour gas and oil wells. The nickel content in the alloy provides the resistance to chloride ion and stress corrosion cracking. The alloy has excellent anti- oxidation and non-oxidizing heat acid performance which comes from the chromium content. The titanium content, often with heat treatment, sustains to resists inter-granular attack after fabrication and pitting. Inconel 825 has good mechanical properties for a range of temperatures from cryogenic to moderately high temperatures. The alloy has comparatively good weldability by all conventional mechanism. It can be easily hot or cold worked.

The special properties of Inconel 825 Buttweld Fittings make them highly useful and in great demand. There are many specialised types of Inconel 825 Pipe fittings used in the industry and are highly cost effective. Most of the Pipe fittings in standard sizes and grades are available in stock for immediate supply to our customers.
