304 Stainless Steel Foil Sheet — Precision Thin Steel Plate for DIY & Fabrication

When a project demands exact material thickness and reliable corrosion resistance, standard sheet metal often falls short. Machinists, fabricators, and hands-on DIYers who need ultra-thin 304 stainless steel foil sheet in controlled dimensions know how difficult it is to source the right gauge without ordering bulk quantities or accepting inconsistent tolerances.

Each sheet is 304-grade stainless steel — an austenitic alloy with a chromium-nickel composition that delivers strong oxidation resistance and structural integrity across a wide temperature range. Sheets measure 300mm × 1000mm (approx. 11.8" × 39.4") with thickness options spanning 0.05mm to 0.8mm (approximately 0.002" to 0.031"). The foil surface is smooth-rolled with consistent gauge throughout.

Typical applications include shim stock for machinery alignment, gasket blanks for plumbing and HVAC assemblies, heat shields in automotive or appliance repair, and precision spacers in electronics enclosures. The 300×1000mm format is well-suited for cutting custom shim strips, wrapping cylindrical components, or laminating into multi-layer assemblies.

✅ Key Features of These 304 Stainless Steel Foil Sheets

• 📏 Wide thickness range: Available from 0.05mm to 0.8mm (0.002"–0.031") — select the exact gauge your application requires without over-ordering.
• 🛡️ 304-grade corrosion resistance: The 18% chromium / 8% nickel composition resists rust, oxidation, and mild chemical exposure, making these sheets suitable for damp or outdoor-adjacent environments.
• 📐 Consistent 300×1000mm format: Each sheet arrives at a uniform 300mm × 1000mm (11.8" × 39.4") — easy to cut down to shim strips, gasket blanks, or custom shapes with standard tooling.
• ⚙️ Smooth-rolled surface finish: The flat, burr-free surface ensures accurate stack-up measurements when used as shim stock or spacer material in precision assemblies.
• 🔥 Temperature-stable alloy: Retains mechanical properties across a broad service range, suitable for heat shields, exhaust wraps, and appliance repair applications.
• ✂️ Machinable and formable: Can be cut with metal snips, scored and bent, laser-cut, or waterjet-cut — no special tooling required for thinner gauges (0.05–0.2mm).
