Incoloy 800 Family Alloys: Welding, Fabrication, and Heat Treatment
The exceptional Incoloy 800 family of materials, renowned for their excellent resistance to degradation at elevated conditions, present unique considerations during fabrication and require careful heat processing to achieve desired mechanical properties. Proper welding procedures, such as using a shielding environment to prevent atmospheric pollution, are crucial. Common welding processes include TIG and shielded metal arc welding. Furthermore, post-weld heat conditioning can alleviate residual tensions and refine the structure. 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 alteration of the alloy's outstanding high-temperature strength. Careful selection of filler alloys matching the base material composition ensures a compatible and robust weld joint.
