2205 Duplex Polished Stainless Steel Flat Bar Food Processing Equipment
2205 Duplex Polished Stainless Steel Flat Bar is a high-performance material widely used in food processing equipment. This material combines the advantages of both austenitic and ferritic stainless steels, offering excellent corrosion resistance and mechanical properties, making it ideal for various food processing environments.

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)
The use of 2205 Duplex Polished Stainless Steel Flat Bar in food processing equipment is extensive, including but not limited to:
