Grade: AISI 302
Formula: Fe/Cr 18/Ni 8
Form: Foil/Film/Sheet
Material: Stainless Steel
Commodity: Alloys
Temper:
Hard
AISI 302 Stainless Steel Foil is an austenitic stainless steel in precision thin-sheet form, combining high corrosion resistance, excellent tensile strength, and reliable ductility. Its slightly higher carbon content than 304 stainless steel allows greater strength after cold working without sacrificing toughness, making it valuable for both structural and functional components in constrained geometries. In foil form, it finds extensive use in electronics, automotive, and aerospace industries for flexible shielding layers, high-strength diaphragms, and precision spring laminates. Specific applications include catalyst carrier substrates in emission control systems, optically smooth substrates for flexible displays, and resilient layers in thermal or radiation shielding assemblies. In research and innovation, 302 stainless foil enables the development of high-performance flexible substrates, fatigue-resistant microstructures, and multi-layer composites for extreme environments. Its blend of mechanical resilience, corrosion protection, and adaptability ensures it remains a critical material in advanced industrial and scientific engineering
