SS 409 Plattenpreis
SS 409 plate is a practical ferritic stainless steel material known for its heat resistance, Oxidationsbeständigkeit, and cost-effective performance. Its titanium-stabilized composition makes it suitable for exhaust systems, industrial heating equipment, and structural fabrication. For applications requiring stronger corrosion resistance, 304 oder 316 stainless steel may be preferred, während 409 remains a reliable option for high-temperature industrial use.
- Beschreibung
SS 409 plate is a ferritic stainless steel plate widely used in applications requiring good oxidation resistance, Wärmewiderstand, and cost-effective corrosion protection. Although the keyword includes “price,” the value of SS 409 plate is mainly influenced by its material composition, Dicke, Oberflächenbeschaffenheit, und Verarbeitungsanforderungen. Gegenüber 304 Edelstahl, 409 offers lower chromium content but better economy for structural and high-temperature applications.
What Is SS 409 Platte?
SS 409 plate is a chromium-based ferritic stainless steel that contains low nickel and added titanium for improved stabilization. It is commonly used in environments where moderate corrosion resistance and high-temperature durability are required. Aufgrund seines ausgewogenen Legierungsdesigns, 409 stainless steel is frequently chosen for automotive exhaust systems, industrial heat equipment, and structural applications.
This grade is magnetic and cannot be hardened by heat treatment, but it provides excellent weldability and good resistance to oxidation.
Chemische Zusammensetzung von SS 409 Platte
The alloy composition of SS 409 plate gives it good thermal stability and resistance to atmospheric corrosion.
| Element | Inhalt (%) |
|---|---|
| Kohlenstoff (C) | ≤ 0.08 |
| Chrom (Cr) | 10.5 – 11.75 |
| Nickel (In) | ≤ 0.50 |
| Mangan (Mn) | ≤ 1.00 |
| Silizium (Und) | ≤ 1.00 |
| Phosphor (P) | ≤ 0.045 |
| Schwefel (S) | ≤ 0.03 |
| Titan (Von) | 6×C min |
| Eisen (Fe) | Gleichgewicht |
The addition of titanium improves weldability and helps prevent intergranular corrosion during high-temperature service.

Main Performance Characteristics
Hitzebeständigkeit
SS 409 plate offers good oxidation resistance at elevated temperatures and is commonly used in continuous service up to approximately 675°C.
Korrosionsbeständigkeit
The material provides adequate resistance to atmospheric corrosion, exhaust gases, and mild industrial environments. It performs better than carbon steel but lower than 304 stainless steel in humid or chloride-rich conditions.
Schweißbarkeit
Because of titanium stabilization, SS 409 plate has good weldability and is often processed by laser cutting, Schweißen, und formen.
Kosteneffizienz
Due to its low nickel content, SS 409 is considered a more economical stainless steel grade for applications that do not require premium corrosion resistance.
