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 Al content, making it ideal for reformer tubes and heat exchangers. Finally, Incoloy 825, a more complex composition 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 engineering.
Incoloy 800 Family Alloys: Welding, Fabrication, and Heat Treatment
The remarkable Incoloy 800 family of metals, renowned for their high resistance to corrosion at elevated temperatures, present unique difficulties during welding and require careful heat treatment to achieve desired mechanical properties. Proper welding procedures, such as using a shielding environment to prevent atmospheric impairment, are crucial. Common welding applications include TIG and shielded metal arc welding. Furthermore, post-weld heat conditioning can alleviate residual tensions and refine the crystal. Fabrication often involves conventional approaches, although specialized tooling might be necessary to account for the alloy's relative work hardening characteristics. Failure to adequately control the heat input during welding and fabrication can lead to embrittlement or change 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.
