100*100mm Thickness 0.01-1mm 301 Stainless Steel Sheet Thin Foil Belt Plate

Measure the gap you need to fill with a feeler gauge or dial indicator, then select the closest single thickness or combine multiple sheets to reach your target dimension. For example, a 0.35mm gap can be filled with one 0.25mm sheet plus one 0.1mm sheet. Order a 3-pack or 5-pack if you anticipate stacking or trial-fitting multiple layers.

301 in spring temper has a tensile strength typically in the range of 860–1275 MPa depending on the degree of cold work, which is higher than annealed 304. For thicknesses of 0.5mm and above, it handles moderate compressive shim loads well. For very thin gauges (0.01–0.1mm), the sheet is better suited to light-contact, sealing, or electrical applications rather than heavy structural loads.

301 stainless resists rust in normal indoor conditions and light outdoor exposure thanks to its passive chromium oxide layer. In continuously wet, salt-spray, or chemically aggressive environments, surface staining or pitting can occur over time. For harsh outdoor or marine use, 316-grade stainless would offer better corrosion resistance. These sheets are well-suited for indoor machinery, electronics enclosures, and protected mechanical assemblies.

Thinner gauges (0.01–0.3mm) can be cut with sharp scissors, a craft knife, or tin snips. Gauges from 0.4mm to 1mm are best cut with aviation snips, a metal shear, or a rotary tool with a cutting disc. Punching is feasible with a hand punch for thicknesses up to about 0.5mm; thicker sheets benefit from a bench punch or hydraulic press. Always deburr cut edges before handling.

Yes, stainless steel shim stock is commonly used as a base for metal gaskets in low-to-medium pressure fluid applications. The 0.1–0.5mm range is most practical for gasket blanks. For a reliable seal, the mating surfaces must be flat and the gasket should be cut to match the flange profile precisely. These sheets are not pre-coated with any sealant compound; apply a suitable gasket sealant if required by your application.

Both are austenitic stainless steels with similar corrosion resistance in standard environments. The key difference is that 301 has a lower nickel content and work-hardens more rapidly, making it stiffer and springier after cold rolling — which is why it is preferred for spring contacts, clips, and shim stock where some resilience is needed. 304 is softer and more formable but does not develop the same spring-back characteristics. For shim and foil applications where dimensional stability and slight spring tension matter, 301 is the more appropriate choice.
