If you are searching for a thin, durable, and corrosion-resistant stainless steel material for industrial, chemical, or electronic applications, SS 304 Annealed Foil is an excellent choice.
SS 304, an austenitic stainless steel, is widely known for its excellent corrosion resistance, high ductility, and good mechanical properties. When produced as foil and annealed, it becomes extremely flexible, easy to form, and suitable for precision applications like gaskets, heat exchangers, battery components, and industrial shields.Annealing is a heat treatment process that relieves internal stresses and enhances ductility, making the foil suitable for high-precision manufacturing and repeated bending without cracking.
Whether you require sample testing or bulk orders, GNEE accommodates flexible MOQs (minimum order quantities) and delivers highly competitive pricing to meet your needs.
In addition, we can provide MTC 3.1 certificates that comply with international standards such as ASTM, ensuring the reliability of our product quality. To facilitate early quality inspection, we can offer samples of 1-2 meters. If you have any project requirements, please feel free to contact us!
