316L Stainless Steel Foil

Precision Specifications

Qihong supplies 316L Stainless Steel Foil in a wide range of specifications to meet different fabrication and component requirements.

Custom thickness, width, hardness, tolerance, and surface requirements can be evaluated according to specific production needs.

Corrosion Resistance and Material Performance

The key advantage of 316L Stainless Steel Foil is its excellent resistance to pitting and crevice corrosion in chloride-containing environments. The addition of molybdenum provides improved corrosion resistance compared with conventional 304 stainless steel, making the material suitable for marine, chemical, and other demanding operating conditions.

Its low carbon content also improves resistance to intergranular corrosion after welding. Combined with good formability and stable mechanical properties, the material is widely used in applications requiring both durability and precision processing performance.

Precision Processing Options

Qihong supplies precision foil with thicknesses from 0.01 mm and widths from 1.5 mm to 600 mm. Slitting, shearing, and edge-processing services help customers receive material in dimensions suitable for their manufacturing process.

Surface finishes including BA, 2B, and 8K are available for different appearance and functional requirements. Hardness conditions such as ANN, 1/4H, 1/2H, and H can be selected according to stamping, bending, etching, or forming processes.

Typical Applications

Thanks to its combination of corrosion resistance, thin-gauge precision, and processing stability, 316L Stainless Steel Foil is widely used in precision connectors, electronic components, medical devices, surgical instruments, lithium battery parts, photovoltaic components, automotive diaphragms, piston ring expanders, and other precision-engineered products.

Material selection should be based on the component design, fabrication process, service environment, and applicable industry standards.
