AISI 304 Stainless Steel Foil

AISI 304 Stainless Steel Foil is an austenitic chromium-nickel alloy known for its excellent formability, corrosion resistance, and mechanical strength. This foil demonstrates high ductility, toughness at cryogenic temperatures, and excellent fatigue and oxidation resistance. A key advantage lies in its ability to maintain integrity at elevated temperatures while offering easy weldability and consistent chemical stability. The foil exhibits moderate work hardening and a relatively low thermal conductivity, making it resilient under mechanical and thermal cycling. Precision-rolled to meet strict dimensional tolerances, AISI 304 foil is also noted for its clean surface finish and low porosity. It is broadly employed in the aerospace, automotive, and electronics sectors. Specific uses include heat exchanger elements, turbine engine insulation wraps, structural foils for honeycomb composites, and contamination barriers during heat treatment of tool steels. In advanced R&D, it plays a role in hydrogen fuel cell assemblies, sensor housings, and flexible substrate platforms for microelectronic circuits. Its well-balanced performance profile makes it a cornerstone material in precision-engineered systems and innovation-driven industrial environments.
