Super Duplex Steel S32760, also known as UNS S32760 or Zeron 100, is a high-performance alloy known for its exceptional corrosion resistance and mechanical strength. Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of S32760 needle tubes. These tubes are exported worldwide, including to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions across Africa, serving industries that demand durability and reliability.
The S32760 needle tubes have a balanced microstructure of austenite and ferrite, which provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Their typical chemical composition includes 24–26% chromium, 6–8% nickel, 3–4% molybdenum, 0.14–0.20% nitrogen, with the balance being iron. This unique combination ensures outstanding performance in chloride-rich and harsh industrial environments.
Super Duplex Steel S32760 exhibits remarkable mechanical strength, making it suitable for high-pressure and high-temperature applications. The tensile strength ranges from 800–1000 MPa, yield strength between 550–750 MPa, elongation around 25%, and hardness approximately 290–330 HB. These properties allow the tubes to withstand demanding industrial conditions without deformation or failure.
S32760 needle tubes are compatible with several international standards, making them highly versatile. Equivalent grades include Werkstoff No. 1.4501, UNS S32760, ASTM/ASME A789/A790, and EN X2CrNiMoN25-7-4. These equivalents allow engineers and designers to select S32760 for projects requiring global standard compliance.
