General purpose alloys
General corrosion resistance refers to atmospheric resistance at 78 °F (25 °C)
Corrosion resistance increases with increased alloy content
Cost increases as alloy content increases
| SAE type | Carbon | Manganese | Silicon | Chromium | Nickel | . | |
| Austenitic | 304 | 0.07 max | 2.00 max | 0.75 max | 17.5 –19.5 | 8.0 -10.5 | Good general corrosion resistance Fair annealed strength Good cold-worked strength High ductility and toughness |
| Ferritic | 430 | 0.12 max | 1.00 max | 1.00 max | 16.0 -18.0 | — | Moderate general corrosion resistance Fair annealed strength |
| Martensitic | 410 | 0.15 max | 1.00 max | 1.00 max | 11.5 -13.0 | — | Fair general corrosion resistance High strength |
