Stainless Steel Foil is a thin, high-precision rolled product typically used in applications requiring extreme thinness, excellent surface finish, and superior corrosion resistance. Manufactured from high-quality austenitic stainless steel grades such as 304, 316, and 321, these foils are used in industries like electronics, medical, aerospace, automotive, and insulation due to their formability, strength, and thermal resistance.

Foils are produced using cold rolling techniques and are available in soft annealed or hardened tempers depending on the intended use. The surface finish is typically smooth, bright, or mirror-like, with precise thickness tolerances.

304 Stainless Steel Foil is an ultra-thin, precision-rolled flat product made from austenitic grade 304 stainless steel, known for its excellent corrosion resistance, flexibility, and durability. Because of its thin profile (typically less than 0.2 mm), it is ideal for precision applications in sectors such as electronics, medical devices, chemical processing, and aerospace.

The foil retains all the desirable properties of 304 stainless steel, including non-magnetic behavior in the annealed condition, excellent formability, and resistance to oxidation, moisture, and many chemicals. It also offers outstanding surface quality and is easy to clean and fabricate, even at very thin gauges.

202 Stainless Steel Foil is a thin, flexible stainless steel product made from austenitic grade 202, offering a cost-effective alternative to 304 foil while delivering good strength, moderate corrosion resistance, and excellent formability. It contains lower nickel and higher manganese content compared to 304, making it more economical and stable in price-sensitive markets.

With a typical thickness range of 0.01 mm to 0.2 mm, SS 202 foil is ideal for lightweight applications that demand durability and easy fabrication. It is widely used in packaging, automotive, construction, and electrical components, particularly where corrosive conditions are mild to moderate.

316L Stainless Steel Foil is an ultra-thin, precision-rolled material made from low-carbon AISI 316L stainless steel, designed for high-performance environments requiring excellent corrosion resistance, flexibility, and formability. With added molybdenum (2–3%), Grade 316L offers superior resistance to pitting, crevice corrosion, and chemical attack, especially in marine, medical, and cleanroom applications.

The “L” (low carbon) variant minimizes carbide precipitation during welding and high-temperature processing, ensuring greater resistance to intergranular corrosion and better weldability. This makes 316L foil ideal for delicate components, thermal shielding, and sterile environments.
