2205 Duplex Stainless Steel Plate - ASTM A240/A182 Grade UNS S32205/S32206
2205 duplex stainless steel plate represents a specialized category of corrosion-resistant alloy that combines austenitic and ferritic microstructures in approximately equal proportions. This dual-phase composition delivers exceptional mechanical strength—nearly double that of conventional austenitic grades—while maintaining superior resistance to stress corrosion cracking and pitting in chloride-rich environments. Engineered for demanding industrial applications including offshore oil and gas platforms, chemical processing equipment, and desalination plants, this material serves critical roles where standard stainless steels fail to meet performance requirements.
What is 2205 Duplex Stainless Steel Plate?
2205 duplex stainless steel plate is a nitrogen-enhanced ferritic-austenitic alloy conforming to UNS S32205/S32206 designation, characterized by a balanced microstructure containing 40-60% ferrite in an austenitic matrix. Manufactured according to ASTM A240/A240M standards, this material exhibits a minimum yield strength of 450 MPa and demonstrates outstanding resistance to chloride-induced corrosion mechanisms that commonly affect single-phase stainless steels in marine and chemical processing environments.

2205 Duplex Stainless Steel Plate Technical Specifications
The chemical composition comprises 21-23% chromium, 4.5-6.5% nickel, 2.5-3.5% molybdenum, and 0.14-0.20% nitrogen per ASTM A240 Section 6, delivering a Pitting Resistance Equivalent Number (PREN) exceeding 35. Mechanical properties include tensile strength of 620-880 MPa, elongation minimum 25% in 50mm gauge length, and Charpy V-notch impact energy of 60J at -40°C. Standard plate thicknesses range from 3mm to 100mm with widths up to 2500mm, supplied in hot-rolled, solution-annealed condition at 1020-1100°C.
Why Choose Our 2205 Duplex Stainless Steel Plate
Our manufacturing facility maintains ISO 9001:2015 and PED 2014/68/EU certifications, ensuring full traceability through mill test certificates per EN 10204 Type 3.1. Each plate undergoes ultrasonic testing per ASTM A435 and dimensional verification to ASTM A480 tolerances. We stock material certified to NACE MR0175/ISO 15156 for sour service applications and provide custom heat treatment services including stress relieving at 300-400°C for fabrication requirements. Factory-direct pricing eliminates distributor markups while maintaining delivery schedules of 15-25 days for standard dimensions.

Frequently Asked Questions
What is the minimum order quantity (MOQ)?
Our standard MOQ is 1 metric ton for stock dimensions. For custom thicknesses or special width requirements, the minimum order increases to 3 metric tons to optimize production efficiency. Sample pieces of 200x200mm are available for material qualification testing prior to bulk orders.
Do you provide material test certificates?
Yes, all shipments include EN 10204 Type 3.1 mill test certificates documenting chemical analysis by optical emission spectrometry, mechanical testing results, heat treatment parameters, and third-party inspection verification. Additional certifications such as NACE compliance, PMI reports, and ultrasonic testing records are available upon request at no extra charge.
What is the typical delivery time?
Stock thickness plates (6mm, 8mm, 10mm, 12mm) ship within 7-10 business days ex-works. Custom thickness production requires 20-30 days including solution annealing and quality inspection. Express processing is available for critical projects with 15-day lead times, subject to production capacity and 15% expedite fee.
Can you cut to custom sizes?
Our precision cutting services include plasma cutting for plates up to 80mm thickness (tolerance ±3mm), waterjet cutting for complex geometries (tolerance ±0.5mm), and shearing for straight cuts on material up to 25mm thick. Edge preparation options include beveling at 30-45° angles for welding preparation and surface grinding to Ra 3.2μm finish. Custom cutting adds 3-5 days to standard delivery schedules.
