Description

ASTM A790 S32205 Seamless Duplex Stainless Steel Tube High Strength Corrosion Resistant for Offshore Applications

YUHONG GROUP​​ is a specialized manufacturer of ​​high-performance duplex stainless steel products, with over 30 years of expertise in serving global energy and chemical industries. Our ​​ASTM A790 S32205 Seamless Duplex Stainless Steel Tubes​​ combine superior corrosion resistance with exceptional mechanical strength for the most demanding applications.

Heat Treatment Requirements for UNS S32205

Parameter​​ ​​Requirement​​
​​UNS Designation​​ S32205
​​Type​​ 2205
​​Temperature Range​​ 1870–2010 °F [1020–1100 °C]
​​Quenching Method​​ Rapid cooling in water or by other means

​Chemical Composition of UNS S32205

Element​​ ​​Requirement (%)​​ ​​Notes​​
​​Carbon (C)​​ ≤0.030 Controls carbide formation
​​Manganese (Mn)​​ ≤2.00 Improves hot workability
​​Phosphorus (P)​​ ≤0.030 Minimizes brittleness
​​Sulfur (S)​​ ≤0.030 Enhances machinability
​​Silicon (Si)​​ ≤1.00 Deoxidizer and strength enhancer
​​Nickel (Ni)​​ 4.5-6.5 Austenite stabilizer
​​Chromium (Cr)​​ 22.0-23.0 Primary corrosion resistance
​​Molybdenum (Mo)​​ 3.0-3.5 Pitting resistance enhancer
​​Nitrogen (N)​​ 0.14-0.20 Strength and corrosion resistance

Tensile and Hardness Requirements for UNS S32205

Property​​ ​​Requirement​​ ​​Unit​​
​​UNS Designation​​ S32205 -
​​Type​​ 2205 -
​​Tensile Strength, min​​ 95 [655] ksi [MPa]
​​Yield Strength, min​​ 65 [450] ksi [MPa]
​​Elongation in 2 in. or 50 mm, min​​ 25 %
​​Hardness, max (HBW)​​ 290 HBW
​​Hardness, max (HRC)​​ 30 HRC

​​ASTM A790 S32205 Seamless Duplex Stainless Steel Tube - Key Application Advantages​

1. Superior Mechanical Strength for Offshore Structures​​

​​Minimum yield strength 450 MPa (65 ksi)​​ withstands extreme ocean wave loads and high-pressure drilling operations

​​25% minimum elongation​​ provides critical ductility to absorb dynamic stresses in subsea pipelines

​​2. Unmatched Corrosion Resistance in Marine Environments​​

​​PREN ≥ 35​​ (Cr+3.3Mo+16N formula) prevents pitting/crevice corrosion in chloride-rich seawater

​​Resists stress corrosion cracking (SCC)​​ under tension in the splash zone and submerged conditions

​​3. Long-Term Reliability in Critical Applications​​

​​50+ year service life​​ in North Sea oil platforms (documented cases)

​​Maintenance cost reduction​​ up to 60% compared to 316L systems through eliminated cathodic protection needs

​​4. Operational Safety Enhancements​​

​​Inherent fire resistance​​ maintains structural integrity at high temperatures (PED compliance)

​​Zero toxicity leaching​​ ensures compatibility with seawater cooling for LNG processing
