| TypeMetallurgical family — determines magnetism and how it's strengthened. | Austenitic |
|---|---|
| ConditionThe condition these typical values apply to. | Annealed |
| Density(g/cm³) | 8 |
| Tensile(MPa)Typical ultimate tensile strength. | 485 |
| Yield(MPa)Typical 0.2% offset yield strength. | 170 |
| Elong.(%)Typical elongation at break. | 40 |
| HardnessTypical hardness (annealed unless noted). | ≤201 HB |
| Machinability | Fair |
| Magnetic | No* |
- Typical uses: welded tanks and piping, heavy-gauge welded fabrications.
- Slightly lower strength than 304 in exchange for weldability.
