Ss 409 Harga Pinggan
SS 409 plate is a practical ferritic stainless steel material known for its heat resistance, rintangan pengoksidaan, and cost-effective performance. Its titanium-stabilized composition makes it suitable for exhaust systems, industrial heating equipment, and structural fabrication. Untuk aplikasi yang memerlukan rintangan kakisan yang lebih kuat, 304 atau 316 stainless steel may be preferred, sementara 409 remains a reliable option for high-temperature industrial use.
- Penerangan
SS 409 plate is a ferritic stainless steel plate widely used in applications requiring good oxidation resistance, rintangan haba, and cost-effective corrosion protection. Although the keyword includes “price,” the value of SS 409 plate is mainly influenced by its material composition, ketebalan, kemasan permukaan, dan keperluan pemprosesan. Berbanding dengan 304 keluli tahan karat, 409 offers lower chromium content but better economy for structural and high-temperature applications.
Apa Itu SS 409 Pinggan?
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. Because of its balanced alloy design, 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.
Komposisi Kimia SS 409 Pinggan
The alloy composition of SS 409 plate gives it good thermal stability and resistance to atmospheric corrosion.
| unsur | kandungan (%) |
|---|---|
| Karbon (C) | ≤ 0.08 |
| Chromium (Cr) | 10.5 – 11.75 |
| Nikel (Dalam) | ≤ 0.50 |
| Mangan (Mn) | ≤ 1.00 |
| silikon (Dan) | ≤ 1.00 |
| Fosforus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.03 |
| titanium (Daripada) | 6×C min |
| Besi (Fe) | Keseimbangan |
The addition of titanium improves weldability and helps prevent intergranular corrosion during high-temperature service.
Sifat Mekanikal SS 409 Pinggan
SS 409 plate provides moderate strength and good formability for industrial fabrication.
| Harta benda | Nilai Biasa |
|---|---|
| Kekuatan Tegangan | ≥ 380 MPa |
| Kekuatan Hasil | ≥ 170 MPa |
| Pemanjangan | ≥ 20% |
| Kekerasan | ≤ 88 HRB |
| Ketumpatan | 7.7 g/cm³ |
| Julat Lebur | 1450 – 1510°C |
Its ferritic structure makes it suitable for forming, membengkok, and welding in sheet and plate applications.
Ciri-ciri Prestasi Utama
Rintangan Haba
SS 409 plate offers good oxidation resistance at elevated temperatures and is commonly used in continuous service up to approximately 675°C.
Rintangan Kakisan
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.
Kebolehkimpalan
Because of titanium stabilization, SS 409 plate has good weldability and is often processed by laser cutting, mengimpal, dan membentuk.
Cost Efficiency
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.
