304 Stainless Steel Thin Plate Band Thick 0.01mm~1mm Metal Strip Roll Foil Sheet

Measure the gap with a feeler gauge set, then choose the closest thickness option. For stacked shims, combine two or more thin strips (e.g., two 0.05 mm pieces to achieve 0.1 mm). Gauges from 0.01 mm to 0.05 mm are typically used for fine bearing alignment and precision machinery, while 0.1 mm to 0.5 mm suits general mechanical shimming, gasket blanks, and thin backing plates.

304 stainless steel thin strip is not intended as a primary structural member. Its annealed tensile strength is approximately 515 MPa, which is adequate for shims, spring elements, heat shields, and thin brackets. For load-bearing structural components, consult an engineer and consider thicker plate stock rather than foil-gauge material.

304 stainless steel forms a self-healing passive oxide layer that resists rust in most atmospheric and mildly corrosive environments, including rain and humidity. It is not recommended for continuous immersion in chloride-rich environments such as seawater or de-icing salt contact — for those conditions, 316 grade is a better choice.

Thin gauges (0.01–0.1 mm) can be cut cleanly with sharp scissors, a craft knife, or tin snips. Gauges from 0.15 mm to 0.5 mm are best cut with aviation snips or a guillotine shear. The 0.6 mm to 1.0 mm strip requires an angle grinder with a cutting disc, a cold saw, or a bandsaw with a bi-metal blade. Always deburr cut edges before handling to avoid injury.

Yes. 304 stainless steel is fully TIG-weldable. Use ER308L filler wire and back-purge with argon when welding thin gauges to prevent oxidation on the reverse side. For foils thinner than 0.1 mm, autogenous (no-filler) TIG welding with a micro-TIG torch is common in precision fabrication. Avoid overheating to minimize heat-affected zone sensitization.

The 100 mm width covers the widest range of shimming and gasket tasks without excessive waste for most workshop applications. If your work is primarily narrow shims (bearing alignment, feeler-gauge replacement), the 50 mm width is more economical. For wide gasket blanks or heat shields, the 200 mm or 300 mm options eliminate the need to join multiple strips.

Use a digital micrometer with 0.001 mm resolution to measure the gap or existing shim you need to match. Thickness values listed in the variant selector are nominal commercial tolerances. If your application requires certified dimensional tolerances (e.g., ISO 9445 or ASTM A480), contact us to confirm before ordering.
