From Wikipedia, the free encyclopedia SAF 2507, also known as Sandvik SAF 2507, is a Sandvik -owned trademark for a 25Cr duplex (ferritic - austenitic) stainless steel. The nominal chemical composition of SAF 2507 is 25% Chromium, 7% Nickel, 4% Molybdenum and other alloying elements such as Nitrogen and Manganese. ASTM A789 ASME SA 789 SAF2507 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. CLI - SAF 2507® has improved corrosion resistance properties when compared to duplex 2205 type materials, or even to URANUS® 47N.
