Why Choose ASTM A240/ASME SA240 UNS S32520 Stainless Steel UR52N Sheet?

 

ASTM A240/ASME SA240 UNS S32520, commonly known as UR52N or Duplex 2507, is a super-duplex stainless steel with 24.0-26.0% chromium, 5.5-8.0% nickel, 3.0-4.0% molybdenum, 0.2-0.35% nitrogen, and 0.5-2.0% copper. Its balanced ferritic-austenitic microstructure provides exceptional strength, nearly twice that of austenitic grades like sa 240/a 240 uns s31600, and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich and acidic environments. This makes it ideal for demanding applications in marine, chemical, and oil and gas industries.

The high molybdenum, nitrogen, and copper content give ASTM A240/ASME SA240 UNS S32520 stainless steel UR52N sheet a pitting resistance equivalent number (PREN) of ~40-43, offering corrosion resistance comparable to sa 240/a 240 uns s32750. 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 S32520 stainless steel UR52N sheet include:

• Exceptional Strength: Nearly twice the yield strength of sa 240/a 240 uns s30400, enabling reduced material thickness and weight.
• Superior Corrosion Resistance: High molybdenum (3.0-4.0%), nitrogen (0.2-0.35%), and copper (0.5-2.0%) provide excellent resistance to chlorides and acids, outperforming sa 240/a 240 uns s32205 in aggressive environments.
• Excellent Weldability: Low carbon content (≤ 0.03%) minimizes intergranular corrosion, suitable for welded structures.
• Versatility: Ideal for harsh environments in marine, chemical, and oil and gas applications.

Case Study: A chemical processing plant in India used sa 240/a 240 uns s32520 sheets for acid storage tanks, achieving a 45% longer service life due to its superior corrosion resistance compared to sa 240/a 240 uns s32205.
