AISI 321 Stainless Steel Foil is a titanium-stabilized austenitic alloy optimized for resistance to intergranular corrosion, oxidation, and scaling at elevated temperatures.
The foil format offers thin, precision-rolled material with high flexibility and surface quality, enabling integration into thermal management systems, chemical process equipment, and precision instrumentation.
It is widely employed in aerospace, automotive, electronics, and chemical industries where high-temperature stability and corrosion protection are critical.
Specific applications include flexible thermal shields, chemical-resistant gaskets, and precision diaphragms in sensors. In research and development, 321 foil is utilized for microfabrication substrates, fatigue and creep resistance testing under thermal cycling, and as a model alloy in coating and surface engineering studies.
Its unique combination of mechanical stability, heat resistance, and formability secures its role in both industrial production and advanced experimental projects.
