Thick 0.01mm - 3mm 301 Stainless Steel Sheet Plate 100mm-500mm Metal Sheets

For shim stock and precision alignment tasks, thicknesses between 0.01mm and 0.1mm are typical. For light structural brackets or cladding panels, 0.3mm–1mm is a common range. For rigid plates that need to bear load or resist bending, 1.5mm–3mm is recommended. If you are unsure, start with a mid-range thickness (0.3mm–0.5mm) and test fit before committing to a larger quantity.

301 stainless steel offers moderate corrosion resistance suitable for indoor and semi-protected outdoor environments. In continuously wet, coastal, or chemically aggressive conditions, 304 or 316 grade stainless is generally preferred. For covered outdoor applications — such as under an eave or inside a weatherproof enclosure — 301 performs reliably without additional coating.

Yes. Thin sheets (under 0.5mm) can be cut with heavy-duty tin snips or a utility knife scored along a straightedge. Sheets from 0.5mm to 1.5mm are best cut with an angle grinder fitted with a stainless-rated cutting disc, or with aviation snips. Sheets 2mm and above typically require a cold saw, plasma cutter, waterjet, or laser cutter for clean edges. Always deburr cut edges before handling.

301 stainless steel is one of the most commonly specified alloys for spring-temper applications because it work-hardens rapidly during cold forming. Thin sheets (0.1mm–0.5mm) bent and released will retain spring-back tension, making them suitable for clips, retaining tabs, contact fingers, and flexible connectors. For maximum spring performance, use the thinner gauges and avoid annealing after forming.

Match the sheet dimensions to your finished part size plus any allowance for cutting waste (typically 5–10mm per edge). The 100×100mm format suits small brackets, shims, and patches. The 100×300mm and 100×500mm formats are useful for strips, channels, and elongated covers. The 200×300mm and 300×300mm formats work well for larger panels, backing plates, and multi-part blanks cut from a single sheet.

Each variant lists the number of identical sheets included in a single order. Selecting 1 Pcs gives you one sheet of the chosen size and thickness. Selecting 2 or 3 Pcs gives you that many sheets at a per-pack price — useful when you need spares, are working on multiple identical parts, or want to test a thickness before committing to a larger quantity. The price per sheet decreases slightly with higher pack quantities.

Yes. 301 stainless steel is weldable using TIG, MIG (with stainless wire and appropriate shielding gas), or resistance welding methods. For thin sheets under 0.3mm, TIG welding with a low amperage setting is recommended to avoid burn-through. Soldering is possible with stainless-compatible flux and silver-bearing solder, though mechanical joints or welding are generally preferred for structural connections.
