304 A2 Stainless Steel Flat Bar-Plate Can be customised thick 6mm 8mm L 0.1-1m

Choose 6 mm (≈0.24 in) for lighter structural brackets, trim pieces, and applications where weight matters. Choose 8 mm (≈0.31 in) when the part will carry higher loads, act as a wear plate, or needs greater rigidity without deflection under bending stress. For load-bearing structural use, always verify your design against the actual yield strength (≥205 MPa for 304) rather than relying on thickness alone.

Select the Size(mm) variant that matches your finished part dimensions, adding any allowance needed for cutting, drilling, or bending setback. Available widths run from 10 mm to 80 mm and lengths from 100 mm to 500 mm in the listed variants. If your project requires a length up to 1,000 mm, contact us to confirm availability of custom-cut pieces before ordering.

304 (A2) stainless performs well in most outdoor environments and resists rust in fresh water and mildly humid conditions. For direct saltwater immersion or coastal spray zones, 316 (A4) grade is generally recommended due to its added molybdenum content. For bracketing, trim, and structural parts in sheltered outdoor settings, 304 flat bar is a practical and cost-effective choice.

Yes. 304 stainless welds readily with TIG (GTAW) using ER308L filler wire, or with MIG (GMAW) using 308L wire and a tri-mix or argon-rich shielding gas. Standard stick welding with E308L-16 electrodes also works. Avoid using carbon steel consumables, as this can introduce rust pathways at the weld zone. Post-weld passivation or pickling is recommended for corrosion-critical applications.

304 stainless steel forms a self-repairing passive chromium oxide layer that prevents bulk rusting under normal conditions. Surface staining (tea staining) can occur in high-chloride environments or if the surface is contaminated with carbon steel particles. Regular cleaning with a mild detergent and avoiding contact with carbon steel tools during fabrication will maintain the appearance and corrosion resistance over time.

Yes. 304 stainless can be cut with an angle grinder (use a stainless-rated cutting disc), cold saw, or bandsaw with bi-metal blades. Drilling requires sharp HSS-Co (cobalt) or carbide-tipped bits, a slow feed rate, and cutting fluid to prevent work hardening. Avoid letting the drill dwell without cutting, as 304 work-hardens quickly and will blunt standard HSS bits.

304 stainless steel is widely used in food-processing equipment frames, conveyor supports, and food-contact surfaces due to its non-reactive surface and ease of cleaning. It meets the general requirements of food-grade metal contact under most regulatory frameworks. For direct food-contact applications subject to specific certifications, verify compliance with your local food safety authority's requirements before use.
