Mirror Polished Shiny Stainless Steel 201 Grade Sheet Metal Plate 0.5mm to 3mm

201-grade stainless steel uses manganese in place of some of the nickel found in 304-grade, which reduces cost while maintaining solid corrosion resistance for indoor and light-outdoor use. For applications exposed to salt air, prolonged moisture, or harsh chemicals, 304 or 316 grade is the more appropriate choice. For decorative panels, trim work, enclosures, and dry-environment fabrication, 201 performs reliably.

Thinner gauges (0.5mm–1mm) are suited to decorative overlays, lightweight trim, and applications where the sheet is supported or bonded to a substrate. Mid-range gauges (1.5mm–2mm) work well for structural panels, enclosure walls, and backsplashes that need to hold their shape without additional backing. Thicker options (2.5mm–3mm) are appropriate when the plate must bear load, resist impact, or serve as a standalone structural element.

Yes. 201 stainless steel can be cut with an angle grinder fitted with a stainless-rated cutting disc, a jigsaw with a bi-metal blade, or tin snips for thinner gauges (0.5mm–1mm). Drilling requires HSS or cobalt drill bits and a slow feed rate with cutting fluid to prevent work-hardening. Avoid using carbon-steel tools without a stainless-rated coating, as they can leave embedded iron particles that cause surface rust.

Mirror-polished surfaces are susceptible to fine scratches from abrasive contact. Handle plates with clean gloves and keep the protective film (if present) in place until installation is complete. For ongoing protection, a thin coat of stainless steel polish or a clear lacquer rated for metal can help maintain the reflective appearance in high-contact areas.

201-grade stainless steel offers moderate corrosion resistance and performs well in covered outdoor settings or environments with low humidity and no salt exposure. For fully exposed outdoor installations, coastal environments, or applications involving prolonged water contact, 304 or 316 stainless steel is the recommended specification.

Use the Size dropdown to choose the plate footprint that matches your project's cut list — all dimensions are stated as finished size. Then select the Thickness that meets your structural or aesthetic requirement. If you need a size or thickness not listed, contact us to confirm whether custom dimensions are available.

Yes. 201 stainless steel is weldable using TIG or MIG processes with a stainless-compatible filler wire and appropriate shielding gas (typically argon or argon/helium mix). It can also be bent on a press brake or folded with sheet metal bending tools. Thicker gauges (2mm and above) require more force and may need annealing if tight-radius bends are required. Post-weld passivation is recommended to restore corrosion resistance at the weld zone.
