Rod nickel alloy 825

for the aerospace industry

Alloy 825 is a titanium stabilised austenitic nickel base alloy with additions of molybdenum and copper. The alloy offers exceptional corrosion resistance in reducing and oxidating environments and provides resistance to chloride stress corrosion cracking and pitting. The addition of titanium in the alloying process stabilises the product against sensitisation in the 'as-welded' condition. The resulting alloy is resistant to intergranular attack in exposed temperature ranges. A similar effect would occur on unstabilised stainless steel. Performance Alloy 825 offers good mechanical properties fromcryogenic to moderately high temperatures. The alloy is readily formable and weldable by various methods. Our product finds use in applications such as oil & gas piping systems, nuclear fuel processing and acids production. Stock Availability Smiths Advanced Metals offers Alloy 825 bars from stock in various sizes to suit your engineering requirements.
