- Description
409 plaque en acier inoxydable (409 SS plate) est un acier inoxydable ferritique widely used in applications requiring bonne résistance à la corrosion, résistance à la chaleur, et rentabilité. It contains chromium as the main alloying element and is stabilized with titanium, which improves its performance at elevated temperatures.
Compared with austenitic grades like 304, 409 offres en acier inoxydable lower cost and adequate performance for many industrial uses, surtout dans automotive and exhaust systems.
Composition chimique de 409 Acier inoxydable
| Élément | Contenu (%) |
|---|---|
| Chrome (Cr) | 10.5 – 11.75 |
| Carbone (C) | ≤ 0.08 |
| Manganèse (Mn) | ≤ 1.00 |
| Silicium (Et) | ≤ 1.00 |
| Titane (De) | Stabilized (typically ≥ 6×C) |
| Phosphore (P.) | ≤ 0.045 |
| Soufre (S) | ≤ 0.030 |
| Fer (Fe) | Équilibre |
The addition of titanium helps prevent intergranular corrosion and improves weldability.
