Ultra-thin 304 Stainless Steel Sheet Plate Roll 0.01-0.6mm Thick 100-600 mm Wide

For EMI/RF shielding and flexible wrapping, foil-grade thicknesses of 0.01–0.03 mm work well. For shim stock and precision spacers, 0.05–0.2 mm provides enough rigidity to hold position. For structural brackets, heat shields, or decorative panels that need to hold their shape under light load, 0.3–0.6 mm is the practical range. When in doubt, order one step thicker — it is easier to remove material than to add it.

304 stainless steel has a tensile strength of approximately 515 MPa (75,000 psi) in its annealed state, which is adequate for light structural and forming tasks. However, at the ultra-thin gauges in this listing (0.01–0.6 mm), the sheet is not intended for primary structural load-bearing. It is suited for shielding, shimming, forming, and decorative applications where the surrounding structure carries the main load.

304 stainless steel resists rust in most indoor environments and light outdoor exposure thanks to its chromium oxide passive layer. It is not recommended for prolonged contact with chloride-rich environments (such as saltwater or de-icing salts) — for those conditions, 316-grade stainless would be more appropriate. Keeping the surface clean and dry extends service life significantly.

Thicknesses of 0.01–0.1 mm can typically be cut with heavy-duty craft scissors, a sharp utility knife against a steel rule, or a rotary cutter. Thicknesses of 0.2–0.6 mm are better suited to aviation snips, bench shears, a laser cutter, or a waterjet. Avoid standard household scissors on gauges above 0.05 mm, as this can damage the blades and produce a ragged edge.

304 stainless steel can be TIG or MIG welded using 308L filler rod. At foil gauges (0.01–0.05 mm), welding requires very low amperage and experienced technique to avoid burn-through. Soldering is possible with stainless-compatible flux, though adhesion is less reliable than on copper or mild steel. For thin-gauge joining, adhesive bonding or mechanical fastening (rivets, screws) is often more practical.

Choose the width closest to — but not narrower than — your finished part dimension to minimize waste. The 100 mm width suits narrow strips, gaskets, and shim rings. The 200 mm width covers most electronics shielding panels and small heat shields. The 300 mm width is useful for larger decorative inlays, broader shim plates, or when you need to cut multiple narrower strips from a single piece.

Standard stainless steel plate typically starts at 3 mm thickness and is used for structural fabrication. This listing covers ultra-thin sheet and foil gauges (0.01–0.6 mm) that are used for shielding, shimming, forming, and surface applications where minimal added thickness and weight are important. The material grade (304) is the same; only the gauge range differs.
