A2 Stainless Steel Foil Sheet 1 Meter Band Roll Strip CNC Thick 0.015mm to 0.5mm

Measure the gap you need to fill with a feeler gauge, then select the foil thickness that matches or can be stacked to reach that dimension. For gaps under 0.1 mm, start with 0.01 mm or 0.02 mm foil and layer as needed. For gaps between 0.1 mm and 0.5 mm, a single-layer foil in the matching thickness is usually sufficient and more stable than a stack.

A2 (304) contains 18% chromium and 8% nickel and performs well in most indoor and outdoor environments. A4 (316) adds 2–3% molybdenum, which significantly improves resistance to chlorides and salt water. For marine, coastal, or chemical-processing environments, A4 is the stronger choice. For general workshop, HVAC, and light outdoor use, A2 is adequate and more cost-effective.

Yes. Thinner gauges (0.01 mm–0.1 mm) cut cleanly with sharp scissors, a craft knife, or a rotary cutter on a cutting mat. Thicker gauges (0.2 mm–0.5 mm) are best cut with aviation snips, a guillotine shear, or a laser cutter for straight, burr-free edges. CNC routers with appropriate end mills also work well for complex shapes.

A2 stainless steel forms a passive chromium-oxide layer that resists rust and staining in most environments. It can discolor if exposed to strong chlorides (such as road salt or bleach) for extended periods. Rinsing with clean water and occasional wiping with a mild stainless cleaner will maintain the surface. For permanently wet or salt-spray environments, consider A4 (316) grade instead.

Select a width that is at least as wide as the widest dimension of your gasket profile. For pipe flanges up to 100 mm OD, the 100 mm or 150 mm width gives enough material to cut the annular shape with minimal waste. For larger flanges or custom shapes, the 200 mm or 300 mm width provides more working area. Always add 10–15% to your measured gasket size to account for cutting margins.

A2 (304) stainless steel is widely used in food-processing equipment and is generally considered food-safe when properly cleaned. However, regulatory compliance for food-contact or medical-device applications depends on your specific jurisdiction and end-use requirements. If your application requires certified food-grade or medical-grade material with full traceability documentation, please contact us to confirm before ordering.

Yes. A2 stainless steel is weldable by TIG, MIG, and resistance-welding methods. Use ER308L filler wire for TIG welding thin gauges to minimize heat distortion. Soldering is possible with appropriate stainless-steel flux, though the joint strength will be lower than a welded connection. For foils thinner than 0.05 mm, adhesive bonding or mechanical clamping is often more practical than welding.
