Alloy 825 Austenitic Nickel-Iron-Chromium Alloy Steel Tubes
Alloy 825 Austenitic Nickel-Iron-Chromium Alloy Tubes
Product Description:
Incoloy 825 is an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It was developed to provide exceptional corrosion resistance in both oxidizing and reducing environments. The alloy is resistant to chloride stress-corrosion cracking and pitting. The addition of titanium stabilizes Alloy 825 against sensitization in the as-welded condition making the alloy resistant to intergranular attack after exposure to temperatures in a range that would sensitize unstabilized stainless steels. The fabrication of Alloy 825 is typical of nickel-base alloys, with material being readily formable and weldable by a variety of techniques.
Alloy 825 Coils can be not and cold worked. Tooling and heavy duty machining equipments are used to reduce work-hardening of this alloy. Inconel 825 Plates is used in the petroleum industry for applications such as gas well components, valves and tubing, as well as finding use in high-strength piping systems. Inconel 825 Sheets is also used in various industry applications such as in Oil & Gas, Hangers, Tool Joints, Fasteners, Shafting and more.
