Sandvik SAF 2304 is a duplex (austenitic-ferritic) stainless steel with a low carbon content. The material is characterized by the following properties:

• Very good resistance to stress corrosion cracking (SCC)

• Good resistance to general corrosion an pitting

• High strength - approximately twice as high proof strength as austenitic stainless steels

• Physical properties that offer design advantages

• Ease of fabrication and good toughness

• Good weldability

Applications
SAF 2304 possesses good mechanical and physical properties, excellent resistance to stress corrosion cracking and other forms of corrosion as well as good weldability. These properties make it both a technically and economically superior alternative to stainless steels such as the austenitic steels AISI 304, 304L, 316, 316L, 321 and 347, the ferritic chromium steels AISI 430 and 444 and the martensitic chromium steels of the AISI 410 and 420 type. SAF 2304 also has advantages in many cases over low-alloy steels. Examples of areas where SAF 2304 offers advantages over other materials are given in the following table.

The good mechanical and corrosion properties make SAF 2304 an economical choice in many applications by reducing the life cycle cost of the equipment.
