Super Duplex 2507
Description
Super duplex 2507 (UNS S32750) is a robust stainless steel alloy formulated for extreme environments. Containing 25% chromium, 4% molybdenum, and 7% nickel, it offers excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Designed for high-strength applications below 316°C, it is widely used in tropical marine systems, offshore oil rigs, and chemical processing where long-lasting durability and corrosion resistance are essential.
Application：
- Offshore oil and gas exploration
- Heat exchangers in chemical processing
- Hydraulic and instrumentation applications
- Chemical process
- Petrochemical
- Seawater equipment
