Stainless Steel Plate Sheet Metal Panel Solid Board Thickness 0.6 0.8 1.0 - 14mm

Thin gauges (0.6 mm – 1.5 mm) work well for enclosure panels, decorative faceplates, and shim stock where weight and formability matter. Mid-range thicknesses (2 mm – 5 mm) suit structural brackets, mounting plates, and weld-on tabs. Thicker plates (6 mm – 14 mm) are appropriate for heavy-duty gussets, machine bases, and applications where rigidity under load is required. When in doubt, size up by one thickness step to maintain a safety margin.

304 stainless steel has a typical tensile strength of approximately 515 MPa and a yield strength of approximately 205 MPa, which is comparable to mild structural steel for many light-to-medium duty applications. For heavy structural loads or high-temperature environments above 870 °C (1600 °F), consult an engineer and consider whether a higher-grade alloy is needed.

304 stainless steel forms a passive chromium-oxide layer that resists rust and staining in most atmospheric and mildly corrosive environments. It performs well in rain, humidity, and light chemical exposure. In coastal or high-chloride environments (e.g., near saltwater), 316-grade stainless is generally recommended for long-term outdoor use. For indoor or sheltered outdoor applications, 304 is typically sufficient.

Yes. Thin plates (under 2 mm) can be cut with aviation snips, angle grinders, or laser/plasma cutters. Thicker plates require an angle grinder with a stainless-rated cutting disc, a cold saw, or a plasma/laser cutter. For drilling, use HSS-Co (cobalt) or carbide-tipped drill bits with a cutting fluid to manage heat and prevent work-hardening. Avoid high-speed dry drilling, which can harden the surface and dull bits quickly.

Yes. 304 stainless steel is readily weldable using TIG (GTAW), MIG (GMAW) with ER308L filler wire, or resistance/spot welding. Use stainless-specific wire and shielding gas (typically argon or argon/CO₂ mix) to avoid contamination. After welding, passivate or pickle the weld zone to restore the corrosion-resistant oxide layer if the application is in a corrosive environment.

Start by measuring the finished part size you need, then add at least 5–10 mm on each dimension to allow for cutting, clamping, and edge cleanup. If your part is 90 × 90 mm, the 100 × 100 mm plate gives you a practical working margin. For rectangular parts, choose the closest option where both dimensions exceed your finished size. The quantity selector (1, 2, or 4 pcs) lets you order exactly what you need for single prototypes or small production runs.

The plates are supplied with a mill or brushed finish typical of flat-rolled 304 stainless stock. For decorative applications requiring a mirror or satin finish, additional polishing with progressively finer abrasive pads (e.g., 120 → 240 → 400 grit) will achieve the desired appearance. The base material accepts polishing well due to its austenitic structure.
