Comparing Incoloy 800, 800H, and 825: A Material Selection Guide
Selecting the appropriate alloy for high-temperature applications often involves careful consideration of several factors. Incoloy 800, 800H, and 825, while sharing a common nickel base, each possess distinctly different traits suited to varying service conditions. Incoloy 800, with its good protection to oxidation and carburization, finds use in furnace components and chemical processing. However, Incoloy 800H offers substantially improved creep strength at elevated temperatures thanks to its higher Alu content, making it ideal for reformer tubes and heat exchangers. Finally, Incoloy 825, a more complex blend containing molybdenum and titanium, provides exceptional corrosion resistance in harsh chemical environments; consequently, it’s favored for seawater applications and acid handling, showcasing a unique range of service capabilities compared to its counterparts. Understanding these nuances is pivotal for making informed choices in material development.
Incoloy 800 Family Alloys: Welding, Fabrication, and Heat Treatment
The outstanding Incoloy 800 family of materials, renowned for their excellent resistance to degradation at elevated situations, present unique difficulties during assembly and require careful heat conditioning to achieve desired physical properties. Proper welding methods, such as using a shielding atmosphere to prevent atmospheric pollution, are crucial. Common welding operations include TIG and shielded metal arc welding. Furthermore, post-weld heat conditioning can alleviate residual forces and refine the crystal. Fabrication often involves conventional practices, although specialized tooling might be necessary to account for the alloy's relative work hardening characteristics. Failure to adequately control the heat application during welding and fabrication can lead to embrittlement or alteration of the alloy's impressive high-temperature strength. Careful selection of filler alloys matching the base material composition ensures a compatible and robust weld joint.
