1M 304 Stainless Steel Band Sheet Foil Thin Steel Plate Strip 0.005-0.5mm Thick

For shim stock and precision gap-filling, thicknesses of 0.005 mm–0.05 mm are typical. For flexible spring elements or gaskets, 0.1 mm–0.3 mm works well. For structural brackets, covers, or enclosures that need to hold shape under load, 0.3 mm–0.5 mm is a more appropriate starting point. If you're unsure, start with a mid-range thickness (0.1 mm–0.2 mm) and test fit before committing to a thinner or thicker variant.

304 stainless steel has a tensile strength typically in the range of 515–720 MPa, which is adequate for many light structural, spring, and bracket applications. However, for heavy load-bearing or high-stress environments, you should consult an engineer and consider whether a thicker gauge or a higher-strength grade (such as 316 or 17-4 PH) is more appropriate for your specific use case.

304 stainless steel forms a passive chromium oxide layer that resists rust and oxidation in most atmospheric conditions, including light rain and humidity. It performs well in most outdoor environments but is not ideal for prolonged exposure to saltwater or highly chlorinated environments — for those conditions, 316-grade stainless is recommended. For typical outdoor DIY and workshop use, 304 is a reliable and cost-effective choice.

Select a width that matches or slightly exceeds your required working dimension to minimize trimming. The 20 mm and 50 mm widths are ideal for narrow shims, edge banding, and small brackets. The 100 mm width suits medium panels, heat shields, and gaskets. The 200 mm and 300 mm widths are best for larger covers, enclosures, or decorative cladding panels where a wider sheet is needed.

Yes. Thinner foil grades (0.005 mm–0.1 mm) can be cut with sharp metal shears or a craft knife and bent by hand. Mid-range thicknesses (0.1 mm–0.3 mm) are suitable for scoring, shearing, and light bending with pliers or a brake. Heavier gauges (0.3 mm–0.5 mm) can be cut with angle grinders, laser cutters, or CNC routers, and are weldable using TIG or MIG processes with appropriate 308L filler wire.

Yes — "18-8" is a common informal designation for 304 stainless steel, referring to its approximate composition of 18% chromium and 8% nickel. AISI 304 and EN 1.4301 are the formal designations used in engineering and manufacturing contexts. All three terms refer to the same alloy family.

Each strip is cut to a nominal 1-meter (1000 mm) length. As with all cut metal stock, a small manufacturing tolerance applies — typically ±5 mm on the cut length. If your application requires a precise finished length, plan to trim to final dimension after receiving the material.
