Usages:
- Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless
The combination of Cr, Mo and Ni convey the good resistance of 2205 to chloride pitting and crevice corrosion
This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications
The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environment
What are the characteristics of Duplex 2205:
- High resistance to chloride stress corrosion cracking
- Resistance to chloride pitting and crevice corrosion
- Good general corrosion resistance
- Good sulfide stress corrosion resistance
- High strength
- Good weldability and workability
In what applications is Duplex 2205 used:
- Chemical process vessels, piping and heat exchangers
- Pulp mill digesters, bleach washers, chip pre-steaming vessels
- Food processing equipment
- Oil field piping and heat exchangers
- Flue gas desulfurization equipment
Available size range for seamless pipes and tubes:
- OD: 6-168mm
- WT: 0.5-15mm
