301 Stainless Steel Sheet Strip Flat Stock Thin Foil Plate Thick 0.05mm-3mm

For shim and gasket applications, 0.05 mm – 0.20 mm is typical. Brackets, clips, and spring elements generally use 0.30 mm – 0.80 mm. Structural patch plates or load-bearing strips usually start at 1.00 mm and above. If you are unsure, measure the gap or existing part with a micrometer and match the closest available variant.

Yes. 301 is specifically chosen for spring-temper strip applications because it work-hardens rapidly during cold rolling, raising its yield strength well above that of 304 at the same gauge. Thin strips (0.05 mm – 0.30 mm) can be bent and will retain spring-back force suitable for retaining clips, contact fingers, and similar parts.

301 stainless steel resists rust in most indoor and sheltered outdoor environments due to its chromium content. However, it is not rated for continuous salt-spray or marine exposure — for those conditions, 316-grade stainless is recommended. Avoid prolonged contact with chloride-rich solutions or dissimilar metals that could cause galvanic corrosion.

Thin gauges (up to ~0.50 mm) can be cut cleanly with sharp tin snips or aviation shears. Thicker pieces (0.50 mm – 3.00 mm) are best cut with an angle grinder fitted with a stainless-rated cutting disc, a jigsaw with a bi-metal blade, or a laser/waterjet cutter. Always deburr cut edges before handling.

301 can be TIG or MIG welded using 308L filler rod. It is not typically soldered with standard electrical solder; use silver-bearing solder and appropriate flux if soldering is required. Note that welding thin gauges (under 0.30 mm) requires careful heat control to avoid warping or burn-through.

The 100 mm wide strip is suited for narrow channel liners, hinge reinforcements, edge banding, and single-row shim stacks. The 300 mm wide sheet covers larger patch areas, panel inserts, or projects where you need to cut multiple narrower strips from one piece. Both widths are available in 500 mm and 1000 mm lengths.

Choose 500 mm if your finished part is under ~450 mm long and you want to minimize offcut waste. The 1000 mm length is more economical per unit area for longer parts or when you need to cut multiple shorter pieces from a single strip. Check the per-piece price difference in the variant selector to confirm which offers better value for your quantity.
