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

Applications
Sandvik SAF 2507 strip can be used in general strip applications where a good corrosion resistance is required. It is especially suitable for

• Seawater applications

• Chloride-containing bleaching environments in the pulp and paper industry

• Chemical industry

In the cold rolled condition Sandvik SAF 2507 is a very good spring material for corrosive environments.

In the annealed condition the combination of high yield strength and good corrosion resistance is inviting to a new design approach for a variety of applications. Especially allowing for non-corrosion protected light weight constructions with a low life cycle cost.
