304 Stainless Steel Thin Plate Sheet 100x100mm Thick 0.01/0.02/0.03/0.04mm-2.5mm

For shim stock and precision gap-filling, thicknesses between 0.01mm and 0.1mm are typical. Gasket applications usually call for 0.1mm–0.5mm depending on the sealing pressure. Structural brackets or rigid backing plates generally use 1mm–2.5mm. If you are unsure, measure the existing gap or consult your assembly drawing for the specified tolerance.

304 stainless steel has a typical tensile strength of ≥515 MPa and yield strength of ≥205 MPa, making it suitable for moderate structural applications. However, at very thin gauges (below 0.1mm), the sheet functions primarily as a foil and is not intended for load-bearing roles. For structural use, select a thickness of 1mm or above and verify that the sheet dimensions meet your engineering requirements.

304 stainless steel forms a self-repairing chromium oxide passive layer that resists rust in most indoor and outdoor-adjacent environments. It performs well against moisture, humidity, and mild acids. However, it is not rated for prolonged exposure to saltwater, chlorinated water, or strong industrial chemicals — for those environments, 316-grade stainless steel is the recommended choice.

Yes. Sheets at 0.5mm and below can typically be cut with heavy-duty tin snips or sharp metal scissors. Thicknesses from 0.5mm to 1.5mm work well with an angle grinder fitted with a thin cutting disc or a jigsaw with a bi-metal blade. For 2mm and 2.5mm sheets, an angle grinder or cold saw is recommended. Laser cutting is compatible across all thicknesses for clean, precise edges.

304 stainless steel is weldable using TIG, MIG, or spot welding processes with appropriate filler wire (ER308L is commonly used). Soldering is possible with stainless-steel-compatible flux, though adhesion is more challenging than with mild steel. Very thin foil gauges (below 0.1mm) require careful heat management to avoid warping or burn-through.

If you need a single sheet for a one-off repair or prototype, the 1-piece option keeps cost minimal. For small batch projects or to have spares on hand, 3 or 5 pieces offer a better per-unit value. The 10-piece pack is suited for ongoing fabrication work, classroom or workshop stock, or projects requiring multiple identical shims or gaskets. Per-unit pricing decreases as quantity increases.

The sheets have a mill-finished or lightly processed surface typical of 304 stainless steel stock. For low-pressure gasket applications, the surface is generally adequate. For high-pressure sealing, you may need to lap or polish the mating surfaces. If a specific surface roughness (Ra value) is required for your application, contact us to confirm before ordering.
