Corrosion Resitance
1. Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
3. Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
Heat Resitance
1. Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
2. Subject to embrittlement when exposed to temperatures above 572°F (300°C) even when exposed for short periods of time; Duplex 2205 is therefore not recommended for use above 572°F (300°C)
Application Areas
The use of 2205 Duplex Polished Stainless Steel Flat Bar in food processing equipment is extensive, including but not limited to:
- Conveyor Belts: Used for transporting food during the production process.
- Mixer Components: Maintains durability while mixing and stirring food materials.
- Cutting Tools: Used for precise cutting of ingredients, keeping edges smooth and suitable for direct food contact.
