Product Description
Duplex 2205 Stainless Steel Sheet 5.0mm Double Strength Chloride Resistance for Offshore Platform Structural Components
Duplex 2205 Stainless Steel Sheet - Double Strength with Superior Chloride Resistance
Our Duplex 2205 Stainless Steel Sheet combines the best properties of austenitic and ferritic stainless steels, delivering twice the yield strength of 316L with outstanding chloride stress corrosion cracking resistance. At 5.0mm thickness, these sheets are engineered for the most demanding offshore oil platform, desalination, and chemical processing applications where standard grades fail prematurely.
Key Features
- Double Yield Strength: Minimum 450 MPa yield strength vs 170 MPa for 316L, enabling thinner wall designs and significant weight savings
- Outstanding Chloride SCC Resistance: PREN ≥35 provides exceptional resistance to stress corrosion cracking in chloride-rich environments
- Superior Pitting Resistance: High chromium (22%), molybdenum (3%), and nitrogen content creates a highly stable passive layer
- Good Weldability: Weldable with standard procedures using duplex-specific filler metals for matching corrosion performance
- High Fatigue Strength: Superior cyclic loading performance critical for offshore structural applications
- Cost-Effective Design: Higher strength allows reduced material thickness, compensating for higher per-kg material cost
Applications
- Offshore oil platform structural components
- Subsea flowlines
- Desalination plant pressure vessels
- Chemical tanker cargo tanks
- Pulp and paper digesters
- Flue gas desulfurization systems
- Seawater cooling systems
- Bridge structural elements in marine environments
Quality Assurance
Full material traceability from melt to final product. Each batch tested per ASTM A923 for absence of detrimental intermetallic phases. Charpy impact testing at -46°C, ferrite content measurement (40-55% target), and corrosion testing per ASTM G48 Method A. NORSOK M-650 and DNV GL certification available upon request.
