Introduce：

ASTM A789 ASME SA 789 SAF 2507 UNS S32750 (EN 10216 - 5 1.4410) Stainless Steel is super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.
S32750 Stainless Steel have enhanced pitting and crevice corrosion resistance when compared with 300-series austenitic stainless steel or conventional duplex alloys. This can be attributed to the enhanced levels of chromium, molybdenum and nitrogen found in these materials. Alloy 2507 is the most common “super” duplex grade.
Usage of Duplex 2507 Pipe S32750 Stainless Steel should be limited to applications below 6000 F (3160 C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
S32750 Stainless Steel possesses excellent mechanical properties. Often a light gauge of S32750 Stainless Steel can be used to achieve the same design strength of a thicker nickel alloy. The resulting saving in weight can reduce the overall cost of fabrication.

Super Duplex Corrosion Resistance

The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.

•High resistance to chloride stress corrosion cracking
•High Strength
•Superior resistance to chloride pitting and crevice corrosion
•Good general corrosion resistance
•Suggested for applications up to 6000 F
•Low rate of thermal expansion
•Combination of properties given by austenitic and ferritic structure
•Good weldability and workability
