A2 Stainless Steel Strip Metal Sheet Foil Plate Roll Thick 0.05-1mm Width 300mm

For precision shimming between mechanical parts, the 0.05mm or 0.1mm options are most commonly used. These ultra-thin gauges compress minimally under load and allow fine adjustment of clearances in bearings, gearboxes, and mounting plates. If you need to fill a larger gap, stack multiple thin sheets rather than jumping to a thicker gauge.

A2 (304) stainless has a typical tensile strength of 515–720 MPa, which is adequate for light-duty brackets and support plates. For structural applications carrying significant dynamic loads, the 0.5mm or 0.8mm variants provide more rigidity. If your application involves heavy cyclic stress, consult a structural engineer to confirm suitability.

A2 stainless steel performs well in indoor and sheltered outdoor environments. Its passive chromium-oxide layer resists rust and staining from fresh water, mild cleaning agents, and food acids. However, prolonged exposure to salt spray, chlorinated water, or industrial chemicals can cause surface pitting over time. For marine or pool environments, 316-grade stainless is a better choice.

Yes — gauges up to 0.3mm can be cut cleanly with aviation snips, a sharp craft knife and straightedge, or a rotary cutter on a cutting mat. Thicker gauges (0.4–0.8mm) are better suited to metal shears, an angle grinder with a thin cutting disc, or a CNC router with a carbide bit. Always deburr cut edges with a fine file or sandpaper for safe handling.

Yes. A2 / 304 stainless is readily weldable using TIG welding with ER308L filler rod, or MIG welding with 308L wire. For thin gauges (≤0.2mm), use low amperage and a backing strip to prevent burn-through. Spot welding is also viable for lap joints on thicker gauges. Avoid welding near sensitization temperatures (425–860°C) for extended periods to prevent intergranular corrosion.

If the lining only needs to resist surface abrasion and light impacts (e.g., shelf liner, drawer insert), 0.3mm is sufficient and easier to form around curves. If the lining must withstand repeated mechanical contact, tool impacts, or needs to be self-supporting without a backing substrate, 0.5mm offers noticeably better rigidity and dent resistance.

A2 stainless in the annealed condition has good ductility. Gauges up to 0.3mm can be bent by hand around a straight edge with a minimum bend radius of approximately 1–2× the sheet thickness. Thicker gauges (0.4–0.8mm) should be bent in a sheet metal brake or press brake to achieve clean, crack-free bends. Avoid sharp 90° bends without a radius tool on gauges above 0.5mm.
