Are you looking for high-quality 304 stainless steel plates? We provide ASTM A240 compliant 304 plates in various thicknesses, including 3mm, 6mm, and custom sizes for industrial applications. Whether you need cold-rolled 2B finish or hot-rolled No.1 plate, our stock is ready for quick export.
| Element | Content (%) | Functional Role |
|---|---|---|
| C (Carbon) | ≤0.07 | Low-carbon design reduces risk of intergranular corrosion during welding, meeting food-contact welding requirements. |
| Cr (Chromium) | 17.0–19.0 | Forms Cr₂O₃ passive film to resist oxidative corrosion in food processing environments; oxide film repair rate 0.5nm/h. |
| Ni (Nickel) | 8.0–10.0 | Stabilizes austenitic structure; retains ≥85% toughness at -196℃; prevents protein-deposition-induced corrosion. |
| Mn (Manganese) | ≤2.0 | Controls work hardening index n=0.22, improving formability for deep drawing in food equipment (e.g., beverage can molds). |
