Sandvik SAF 2507® Solution Annealed
Sandvik SAF 2507® Solution Annealed introduction
Sandvik SAF 2507® is a super-duplex (austenitic-ferritic) stainless steel for service in highly corrosive conditions. The grade is characterized by:
Excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments
Excellent resistance to pitting 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
More technical information and charts that are relevant to the materials corrosion, mechanical and physical performance are displayed in the figures on the right side of the material page.
