SAF 2507

SAF 2507, is a Alleima-owned trademark (Formerly Sandvik Materials Technology) 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.^[1] The UNS designation for SAF 2507 is S32750 and the EN steel no. is 1.4410. SAF derives from Sandvik Austenite Ferrite.

Typical properties of SAF 2507 duplex stainless steel are:^[2]

• excellent resistance to stress corrosion cracking in chloride-bearing environments
• excellent resistance to pitting corrosion and crevice corrosion
• high resistance to general corrosion
• very high mechanical strength
• physical properties that offer design advantages
• high resistance to erosion corrosion and corrosion fatigue
• good weldability

• Duplex Stainless Steel
