Super Duplex S32750 is a nitrogen-enhanced duplex stainless steel that combines the desirable aspects of both ferritic and austenitic grades. The alloy exhibits outstanding pitting resistance equivalent number (PREN > 42.5), making it ideal for highly saline and chloride-rich environments. With excellent resistance to stress corrosion cracking, crevice corrosion, erosion, and fatigue, UNS S32750 Tubes are extensively used in marine industries, offshore platforms, desalination plants, heat exchangers, oil & gas pipelines, and power generation sectors.

The high chromium (25%), molybdenum (4%), and nitrogen content of UNS S32750 Super Duplex Tubes ensures low thermal expansion, excellent resistance to localized corrosion, and longer service life. Our tubes are widely accepted in chemical processing industries, subsea equipment, pressure vessels, and other aggressive media applications. Nascent Pipe & Tubes takes pride in being a reliable export partner, offering timely deliveries across the globe. Our technical team provides complete documentation, including third-party inspection certificates, test reports, and ...
... compliance records, ensuring full traceability.
