301 Stainless Steel Sheet Thin Plate Metal Foil Strip Roll Thickness 0.05-0.45mm

Measure the gap you need to fill with a feeler gauge, then select the thickness that matches or can be stacked to reach your target clearance. For most mechanical shimming tasks, 0.05–0.1 mm covers fine adjustments, while 0.2–0.45 mm suits larger gaps or load-bearing shim stacks. Order a 2-pack or 5-pack if you anticipate needing to test multiple layers.

Yes. The 301 grade is specifically chosen for applications requiring spring-like behavior because it work-hardens significantly during cold rolling. Thinner gauges (0.05–0.15 mm) offer more flexibility, while thicker gauges (0.3–0.45 mm) provide greater stiffness and return force. For high-cycle fatigue applications, verify your specific load requirements against the alloy's published tensile data.

301 stainless steel forms a passive chromium oxide layer that resists rust in typical indoor humid conditions, light outdoor exposure, and mild chemical environments. It is not intended for continuous immersion in saltwater or exposure to strong chlorides — for those conditions, 316-grade stainless is more appropriate. For HVAC, plumbing surrounds, and workshop use, 301 performs reliably.

Yes. Gauges up to 0.2 mm cut cleanly with sharp tin snips or a rotary cutter and straightedge. Thicker gauges (0.25–0.45 mm) are best handled with aviation snips, a metal shear, or laser cutting for straight, burr-free edges. Avoid using dull blades — they cause edge deformation on thin foil stock.

Both options share the same 1000 mm length and the same thickness range. The 100 mm width (≈3.94 in) is suited for narrow strips, shims, inlays, and small gaskets. The 300 mm width (≈11.81 in) covers wider heat shields, decorative panels, and gaskets that would otherwise require joining two narrow strips — eliminating a potential weak seam in the finished part.

301 SS can be welded using TIG or MIG processes, but its higher carbon content compared to 304 means there is a greater risk of sensitization (carbide precipitation) in the heat-affected zone. For thin foil gauges, TIG welding with low heat input is recommended. If weld corrosion resistance is critical, consider post-weld passivation or switch to a low-carbon grade like 304L.

Order 1 pcs when you need a single piece for a one-off repair or prototype. Choose 2 pcs for projects requiring paired pieces (e.g., symmetric shims on both sides of a component). The 5-pack offers the best per-piece value for batch fabrication, classroom use, or when you want spares on hand for future repairs of the same type.
