317L molybdenum alloy super corrosion-resistant plate features an austenitic structure with 19Cr-13Ni-3.5Mo, offering outstanding resistance to organic acids and crevice corrosion.
| Element | Content (%) | Role in Corrosion Resistance |
|---|---|---|
| Cr | 18.0–20.0 | Forms passive film, resists oxidation by organic acids; stability of oxide layer in acidic environment improved by 40%. |
| Ni | 11.0–15.0 | Stabilizes austenitic structure, enhances resistance to non-oxidizing acids (e.g., formic acid). |
| Mo | 3.0–4.0 | Enhances resistance to crevice corrosion and organic acids; PREN = Cr% + 3.3×Mo% ≥34, superior to 316L. |
