Dupleks 2205 Lembaran
Dupleks 2205 lembaran offers a unique combination of kekuatan tinggi, rintangan kakisan, dan kecekapan kos, positioning it between standard austenitic stainless steels and super duplex grades.
Berbanding dengan 304, 316, and ferritic steels, 2205 delivers superior performance, while remaining more economical than super duplex materials. It is an ideal choice for perindustrian, marin, and chemical applications requiring durability and reliability.
Siasatan Pantas
- Penerangan
Dupleks 2205 lembaran (AS S32205 / S31803) is the most widely used duplex stainless steel, menggabungkan austenitic and ferritic structures. It offers a superior balance of kekuatan tinggi, rintangan kakisan yang sangat baik, dan kecekapan kos, making it a preferred material in demanding environments.
To better understand its advantages, it is important to compare 2205 with other common stainless steel types, termasuk austenit, ferit, and super duplex grades.
Komposisi Kimia (2205 Dupleks)
| unsur | kandungan (%) |
|---|---|
| Chromium (Cr) | 21.0 – 23.0 |
| Nikel (Dalam) | 4.5 – 6.5 |
| Molibdenum (Mo) | 2.5 – 3.5 |
| Nitrogen (N) | 0.14 – 0.20 |
| Karbon (C) | ≤ 0.03 |
Gubahan ini memberi 2205 itu high resistance to pitting, kakisan celah, dan retakan kakisan tegasan.
