When a project demands a thin, springy metal that holds its shape under repeated stress, most standard sheet stock falls short. Machinists, fabricators, and DIY engineers working on precision shims, flexible springs, gaskets, and custom brackets need a material that combines corrosion resistance with reliable tensile strength — and that's exactly where 301 stainless steel foil sheet delivers.
Each sheet is cut from 301-grade stainless steel strip, a chromium-nickel alloy known for its higher work-hardening rate compared to 304. Sheets measure 300 mm × 1,000 mm (approx. 11.8 in × 39.4 in) and are available in thicknesses ranging from 0.05 mm to 0.45 mm (0.002 in – 0.018 in). The surface finish is a standard mill/bright finish typical of cold-rolled stainless foil. Quantity options of 1, 2, 3, or 5 pieces per order allow you to buy exactly what your project requires.
Typical applications include thin stainless steel shim stock for machinery alignment, flexible spring strips for electrical contacts and clips, corrosion-resistant gasket blanks for fluid systems, and custom-cut decorative or structural panels in model-making and prototyping. The 0.05–0.10 mm range suits ultra-thin shim and foil work, while the 0.15–0.45 mm range is well suited to formed springs and structural strip applications.

301 stainless steel has a lower nickel content than 304, which gives it a higher work-hardening rate. This means 301 becomes significantly stronger and springier when cold-worked or formed, making it the preferred choice for springs, clips, and flexible strips. 304 is more commonly used for general corrosion resistance and formability where spring-back is not required. If your application involves repeated flexing or spring function, 301 is typically the better choice.
Thinner sheets (0.05–0.10 mm) are suited to ultra-thin shim stock, foil gaskets, and applications where minimal material thickness is critical. Mid-range thicknesses (0.15–0.25 mm) work well for flexible spring strips, electrical contact blades, and light structural brackets. Thicker options (0.30–0.45 mm) provide more rigidity and are appropriate for formed springs, heavier shims, and structural strip applications. When in doubt, start with the thinnest thickness that meets your stiffness requirement.
301 stainless steel offers moderate corrosion resistance suitable for indoor environments and low-humidity conditions. It is not recommended for marine, coastal, or highly acidic environments where 316 stainless steel is the standard specification. For outdoor applications with regular moisture exposure, consider whether 316 grade is more appropriate for your project.
Yes. The thinner variants (0.05–0.15 mm) can be cut with sharp metal shears, a craft knife, or laser cutter. Thicker variants (0.20–0.45 mm) are best cut with metal shears, a guillotine cutter, or a laser. Bending can be done with a sheet metal brake or by hand over a straight edge for thinner gauges. Note that 301 work-hardens during forming, so tight bends may require annealing for thicker gauges to avoid cracking.
301 stainless steel forms a passive chromium oxide layer that resists rust and surface staining under normal indoor conditions. However, exposure to chlorides (salt, bleach, or acidic cleaners) can break down this passive layer and cause surface staining or pitting over time. For best longevity, keep the sheet dry, avoid prolonged contact with corrosive chemicals, and wipe clean after handling to remove fingerprint oils.
Each variant listing specifies the quantity: 1, 2, 3, or 5 pieces of the same thickness per order. To receive multiple thicknesses, simply add each thickness variant to your cart separately. All sheets are the same 300 mm × 1,000 mm size regardless of thickness selected.
Yes. The cold-rolled bright finish provides a flat, dimensionally consistent surface that is well suited to shim stock applications in machinery alignment, bearing housings, and tooling setups. The thinner gauges (0.05–0.10 mm) are particularly useful for fine tolerance adjustments. Always verify the actual thickness with a micrometer upon receipt if your application has tight tolerance requirements.
