Why Choose ASTM A240/ASME SA240 UNS S32205 Stainless Steel 2205 Sheet?

 

ASTM A240/ASME SA240 UNS S32205, commonly known as 2205 stainless steel, is an enhanced duplex stainless steel with 22.0-23.0% chromium, 4.5-6.5% nickel, 3.0-3.5% molybdenum, and 0.14-0.20% nitrogen. Its balanced ferritic-austenitic microstructure provides nearly twice the yield strength of austenitic grades like sa 240/a 240 uns s31600, along with superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments. This makes it ideal for marine, chemical, and oil and gas applications.

The higher nitrogen content in ASTM A240/ASME SA240 UNS S32205 compared to sa 240/a 240 uns s31803 enhances its corrosion resistance and strength, with a pitting resistance equivalent number (PREN) of ~35-36. Its high strength, excellent weldability, and resistance to aggressive environments make it a preferred choice for critical applications.

Key benefits of ASTM A240/ASME SA240 UNS S32205 stainless steel 2205 sheet include:

• Superior Strength: Nearly twice the yield strength of sa 240/a 240 uns s30400, allowing for reduced material thickness and weight.
• Enhanced Corrosion Resistance: High molybdenum (3.0-3.5%) and nitrogen (0.14-0.20%) provide superior resistance to chlorides, outperforming sa 240/a 240 uns s31603 in marine environments.
• Excellent Weldability: Low carbon content (≤ 0.03%) minimizes intergranular corrosion, suitable for welded structures.
• Cost-Effective: Moderate nickel content reduces costs compared to high-alloy grades like sa 240/a 240 uns s31254.

Case Study: An offshore oil platform in the UAE used sa 240/a 240 uns s32205 sheets for seawater piping, achieving a 45% longer service life due to its enhanced chloride resistance compared to sa 240/a 240 uns s31803.
