SUS316 Stainless Steel Annealed Foil, 2B Surface Treatment

Are you looking for premium stainless steel foil with excellent corrosion resistance?If your project requires high-quality SUS316 stainless steel foil, our annealed 316 foil with 2B surface finish is the ideal choice. Designed for durability, precision, and long-term performance, it is perfect for applications in chemical processing, electronics, aerospace, and food industries.

 

What is SUS316 stainless steel annealed foil?

SUS316 stainless steel foil is an austenitic corrosion-resistant alloy widely recognized for its excellent performance in harsh environments. SUS316 annealed foil refers to a flexible sheet material that has undergone a softening treatment, making it easy to cut, bend, and form. With a 2B surface finish, it has a smooth, matte surface and is widely used in industrial and decorative applications.

What is the difference between 316 foil and 316L foil?

316L has lower carbon content, making it better for welded applications to reduce intergranular corrosion. Our SUS316 foil is ideal for most general fabrication purposes.

SUS316 Stainless Steel Foil Supplier

We precisely supply full-specification SUS316 stainless steel foil conforming to JIS/ASTM/GB standards, with thicknesses ranging from 0.01-0.5mm and widths from 5-600mm. We support custom orders for cold-rolled hard (H) and soft (2B/BA) conditions, and can also provide value-added processing such as slitting, film coating, and leveling as needed. Free samples are available for testing.

The thickness tolerance of our SUS316 stainless steel foil is precisely controlled to ±0.001mm, with a BA mirror surface roughness of Ra≤0.2μm. The foil surface is free of scratches and pinholes, and the flatness tolerance is ≤0.1mm/m. Raw materials undergo 100% spectral composition testing, and finished products are fully inspected for surface and dimensions roll by roll. Each batch comes with an EN 10204 3.1 MTC material certificate and complies with RoHS/REACH environmental standards. Standard specifications are delivered quickly within 3-5 days, and custom slitting sizes can be completed within 1-3 business days.
