Manufactured using high-quality raw materials, our products comply with international standards such as ASTM A790 UNS S32750 and ASTM A789 / SA 789 UNS S32750, ensuring durability, strength, and reliable performance in demanding environments. As a trusted Super Duplex 2507 Pipes supplier and exporter in India, we cater to global projects with customized solutions across all major industries.
Super Duplex Steel 2507 is a high performance grade of stainless steel with balanced austenite and ferrite microstructure 50/50. This bi-phase alloy containing about 25% chromium, 4% molybdenum, and 7% nickel offers a high degree of mechanical strength, excellent ductility and high level of corrosion resistance. Because of this, Super Duplex Steel 2507 Pipes and Tubes are utilized in chemical processing, marine, offshore oil and gas, pollution control, desalination and food processing industries.
The Tubing 2507 grade is designed with special considerations of critical applications that are high in strength and corrosion resistance. It provides superior performance against chloride-induced stress corrosion cracking (SCC), pitting and crevice corrosion compared to traditional grades of 316L and 904L. These pipes have a minimum tensile strength of 690 Mpa and yield strength of 485 Mpa which ensure that they can withstand high pressure, temperature and mechanical stress in a structural way. They are easily machined, can be stretched at least 20 percent, can withstand temperatures of up to 600 F (315 C) with low thermal expansion, and are the perfect fit in a heat exchanger system.
Super Duplex 2507 Pipes (UNS S32750 Pipes) comes in seamless as well as welded type. Flawless pipes are produced with no weld joints to enhance high pressure applications. Welded pipes are cost effective with great durability. The seamless pipes have sizes between 4 mm and 219 mm and the welded ones have sizes of up to 1219.2 mm with a thickness of 0.5 mm to 20 mm and schedule of SCH 5 to SCH XXS.
2507 Super Duplex tubing is available in multiple forms: round, square, rectangular and U-shaped configurations. They come in annealed and pickled, hot finished, bright annealed or cold drawn conditions and may be polished and surface finished to increase corrosion resistance. Single random, double random and cut-to-length delivery can be ordered to meet project needs.
The material has good resistance to harsh conditions such as chloride-rich and acidic conditions. ASTM A790 UNS S32750 Pipes and SA 789 UNS S32750 Tubes provide a high level of sulfide stress cracking resistance and are commonly used in the offshore, marine, and chemical industries.

Frequently Asked Questions - UNS S32750 Pipes and Tubes
What is Super Duplex Steel 2507 (UNS S32750)?
Super Duplex Steel 2507, designated UNS S32750 or DIN 1.4410, is a high-alloy stainless steel combining approximately 50% austenite and 50% ferrite microstructure. It contains 25% chromium, 4% molybdenum, and 7% nickel, providing superior corrosion resistance and mechanical strength compared to standard austenitic grades.
What is the difference between UNS S32750 and UNS S32760?
Both are super duplex grades, but UNS S32760 contains additional tungsten and copper for enhanced corrosion resistance in more aggressive environments. UNS S32750 (2507) offers excellent general performance, while S32760 (Zeron 100) is preferred in highly corrosive chloride environments. Amardeep Steel supplies both grades.
What standards apply to Super Duplex 2507 Pipes & Tubes?
Super Duplex 2507 Pipes conform to ASTM A790 / ASME SA790 for welded pipes and ASTM A789 / ASME SA789 for seamless and welded tubes. The material complies with international standards from ASME, ASTM, AISI, JIS, EN, and API.
What industries use ASTM A790 UNS S32750 pipes?
Key industries include oil & gas production, offshore marine, chemical and petrochemical processing, water desalination, pulp & paper, power generation, and pollution control systems.
What are the available sizes of Super Duplex 2507 Seamless Pipes?
Seamless pipes range from 1/2" NB to 8" NB (OD 4mm to 219mm), with wall thickness from 0.3mm to 50mm in schedules SCH5 to XXS. Welded pipes are available from 6" NB to 24" NB (OD up to 1219.2mm).
