| Element | Percentage (%) | Role in the Alloy | | :--- | :--- | :--- | | | ≤ 0.08 | Increases hardness but reduces corrosion resistance if too high. | | Silicon (Si) | ≤ 1.00 | Deoxidizer; improves high-temperature oxidation resistance. | | Manganese (Mn) | ≤ 2.00 | Improves hot ductility and workability. | | Phosphorus (P) | ≤ 0.045 | Impurity; kept low to prevent embrittlement. | | Sulfur (S) | ≤ 0.030 | Impurity; improves machinability but reduces corrosion resistance. | | Nickel (Ni) | 8.00 – 10.50 | The key austenite stabilizer. Provides ductility and acid resistance. | | Chromium (Cr) | 18.00 – 20.00 | Forms the passive oxide layer (Cr2O3) that prevents rust. | | Iron (Fe) | Balance | Base element. | | | Manganese (Mn) | ≤ 2
A slightly magnetic response is normal for heavily worked 304. If it is strongly magnetic, it is likely 430 or 201. | | Nickel (Ni) | 8
