301 Stainless Steel Sheet Plate Metal Sheet Foil Sheet Fine Plate Strip Steel

301 stainless steel has a lower nickel content (6–8%) compared to 304 (8–10.5%), which gives it a stronger work-hardening response. This means 301 gets harder and springier as you bend or form it — useful for clips, springs, and retaining strips. 304 is softer and more ductile, better suited for deep drawing or welded enclosures. For flat strip and shim applications where spring-back is desirable, 301 is the more practical choice.

For shims and gap-filling spacers, 0.20–0.30 mm is typically sufficient. For flexible spring clips or retaining tabs, 0.50–0.70 mm provides enough stiffness while remaining formable by hand with pliers. For structural brackets or heat shields that need to hold shape under load, 0.80–1.00 mm is recommended. When in doubt, order one sheet at the thinner end of your range to test formability before committing to a thicker gauge.

301 stainless steel forms a passive chromium oxide layer that resists rust in dry indoor and mildly humid environments. It is not recommended for continuous saltwater exposure or highly acidic environments — for those applications, 316-grade stainless is a better fit. For outdoor use in non-coastal climates, 301 performs well without additional coating, though periodic cleaning with a mild detergent will maintain the surface finish.

Yes. Sheets up to 0.50 mm can be cut cleanly with quality aviation snips or a rotary metal cutter. Thicknesses from 0.60–1.00 mm are best handled with an angle grinder fitted with a thin cutting disc, a metal-cutting jigsaw blade, or a CNC laser cutter. Always deburr cut edges with a fine file or deburring tool before handling, as freshly cut stainless edges are sharp.

Yes, 301 is weldable using TIG or MIG processes. The recommended filler wire is ER308L, which matches the alloy composition closely and minimizes sensitization at the weld zone. Avoid using carbon steel filler, as it will introduce rust points. For thin gauges (0.20–0.50 mm), TIG welding with low amperage and a backing bar is recommended to prevent burn-through.

Choose the width closest to your finished part dimension to minimize waste. If your part is 85 mm wide, the 100 mm sheet gives you a 15 mm trim allowance. If you need multiple narrower strips from one sheet, the 200 mm or 300 mm width lets you cut two or three strips in a single pass. For prototype work, starting with the 100 mm width keeps material cost low while you refine your design.

Order 1 piece when you're prototyping or need a single replacement part. Choose 3 pieces for small-batch projects where you want a spare in case of a mis-cut. The 5-piece option is cost-effective for production runs or when you're making multiple identical parts — the per-sheet price decreases as quantity increases, making it the most economical choice for repeat builds.
