Sandvik 3RE60 is a duplex (austenitic-ferritic) stainless steel characterized by the following properties:

• High resistance to stress corrosion cracking (SCC) in chloride-bearing environments

• Good resistance to general corrosion and pitting

• High mechanical strength - roughly twice the proof strength of austenitic grades

• Good resistance to erosion corrosion and corrosion fatigue

• Physical properties that present design advantages

• Good weldability

Applications
3RE60 is an excellent material for use in chloride-bearing environments where pitting and stress corrosion cracking are potential problems. In such environments, 3RE60 is far superior to the standard austenitic steels. The material is therefore particularly well suited for use in heat exchangers that work with cooling water with moderate chloride contents.

Typical application examples are found in oil refineries, chemical and petrochemical plants and within the pulp industry.

The high strength and hardness of 3RE60 make the material an attractive alternative to the austenitic steels in structures that aresubjected to heavy loads or wear.
