304 Stainless Steel Foil Sheet 0.05/0.06mm - 1mm Thick Fine Plate Strip Steel

For shimming, measure the gap you need to fill with a feeler gauge, then select the thickness closest to that measurement. For fine adjustments, you can stack multiple foil layers. Thicknesses below 0.1 mm are typically used for micro-adjustments in precision machinery, while 0.2 mm–0.5 mm suits most general mechanical shimming tasks. Thicknesses of 0.5 mm–1.0 mm are better suited for structural spacers or heavier-duty applications.

Yes. 304 stainless steel has a tensile strength typically between 515 and 720 MPa, which is sufficient for most static gasket applications involving moderate pressure and temperature. For high-pressure or high-temperature sealing (above 400°C or in aggressive chemical environments), consider 316 or 321 grade instead. For standard plumbing, HVAC, and general mechanical sealing, 304 foil performs reliably.

304 stainless steel forms a passive chromium oxide layer that protects against rust in most environments, including outdoor exposure, freshwater contact, and mild chemical exposure. It is not fully corrosion-proof in chloride-rich environments (such as saltwater or bleach solutions) — for those conditions, 316 grade is recommended. Under normal indoor or light outdoor use, 304 foil will not rust.

Yes, with the right tool for the thickness. Foil under 0.05 mm can be cut with sharp scissors or a craft knife and steel ruler. Thicknesses from 0.05 mm to 0.3 mm work well with tin snips or rotary cutters. For 0.3 mm and above, aviation snips, bench shears, or laser/waterjet cutting give cleaner edges. Avoid using standard scissors on thicker gauges as it can deform the edge.

304 stainless steel can be TIG or MIG welded using 308L filler wire. Very thin foil (under 0.1 mm) requires careful heat control to avoid burn-through; pulse TIG welding is recommended for those gauges. Soldering is possible with stainless-compatible flux, though the bond strength is lower than welding. For most fabrication and repair tasks, TIG welding gives the cleanest result on this material.

Choose a width that is equal to or slightly larger than the widest dimension of the part you need to cut. Ordering a width closer to your finished part size reduces material waste and cutting time. For example, if you need a 90 mm wide gasket blank, the 100 mm width option is the most efficient choice. If you need multiple different widths from one piece, order the widest required and cut down — this is often more economical than ordering multiple narrow strips.

For a single prototype or one-off repair, the 1 m length is usually sufficient and minimises cost. For small batch production (5–20 parts), the 2 m or 5 m option provides enough material with some allowance for test cuts. For ongoing production or when you need to cut many identical pieces, the 10 m length offers the best per-metre value and reduces the frequency of reordering.
