Stainless Steel Sheet Bright Polish 10mm Thick Many Size Grade A2 304 L50-450mm

Measure the footprint your project requires and select the next size up from the dropdown. All sizes are cut dimensions, so what you see is what you receive. If your required size falls between two options, order the larger size and trim to fit using a carbide-tipped blade or angle grinder with a stainless-rated cutting disc.

Yes. At 10mm thick, Grade 304 stainless steel has a minimum yield strength of approximately 205 MPa and tensile strength typically between 515–720 MPa. This makes it well-suited for base plates, mounting flanges, gussets, and other load-bearing fabrication tasks where rigidity and resistance to deformation are required.

Grade 304 (A2) stainless steel forms a self-repairing passive chromium oxide layer that resists rust in most outdoor and humid environments. It performs well in rain, moisture, and mild atmospheric conditions. For highly aggressive environments — such as coastal saltwater spray or strong acid exposure — Grade 316 would be a more appropriate choice.

Yes. Grade 304 stainless steel is readily weldable using TIG (GTAW) or MIG (GMAW) processes. Use 308L stainless filler wire for best results. Avoid prolonged heat input in a single zone to minimise heat-affected zone sensitisation. Post-weld passivation or pickling is recommended for applications where corrosion resistance at the weld seam is critical.

For cutting, use an angle grinder fitted with a stainless-rated (inox) cutting disc, a cold saw, or a plasma cutter. For drilling, use cobalt or carbide-tipped drill bits with a slow feed rate and cutting fluid to prevent work-hardening. Avoid using standard carbon steel tools without lubrication, as 304 stainless can work-harden quickly and dull tooling prematurely.

The bright polish finish is applied to the face surface. The reverse and cut edges will have a mill or saw-cut finish typical of precision-cut flat stock. If a polished finish on all faces is required for your application, contact us to confirm before ordering.

Grade 304 (A2) contains 18% chromium and 8% nickel, offering solid corrosion resistance for most general-purpose and indoor/outdoor applications. Grade 316 (A4) adds 2–3% molybdenum, which significantly improves resistance to chloride pitting — making it the preferred choice for marine, coastal, or chemical processing environments. For most fabrication, architectural, and DIY uses, 304 is the practical and cost-effective option.
