2205 Duplex Steel | SAF 2205
2205 is a duplex (austenitic-ferritic) stainless steel characterized by:
- High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
- High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulphide
- High resistance to general corrosion, pitting, and crevice corrosion
- High resistance to erosion corrosion and corrosion fatigue
- High mechanical strength – roughly twice the proof strength of austenitic stainless steel
- Physical properties that offer design advantages
- Good weldability

Corrosion resistance
General corrosion
Duplex 2205 possesses better resistance to general corrosion than steel of type ASTM TP316L and TP317L. The improved resistance of Duplex 2205 (SAF 2205) is illustrated by the isocorrosion diagram for corrosion in sulphuric acid, and the corrosion rates in mixtures of acetic and formic acid.
Impurities that increase corrosivity are often present in process solutions of acids. If there is a risk of active corrosion, higher alloyed stainless steels should be chosen, e.g. the austenitic grades Sanicro 28, or the super-duplex grade 2507 (SAF 2507).
Welding
The weldability of 2205 duplex steel is good. Suitable welding methods are manual metal-arc welding with covered electrodes or gas shielded arc welding. Welding should be undertaken within the heat input range 0.5-2.5 kJ/mm. Max. interpass temperature is 250°C (482°F). Preheating or post-weld heat treatment is normally not necessary.
Bending
The starting force needed for bending is slightly higher for 2205 duplex steel than for standard austenitic grades (ASTM TP304L and TP316L). 2205 duplex steel can be cold-bent to 25% deformation without requiring subsequent heat treatment. For pressure vessel applications in Germany and the Nordic countries, heat treatment may be required after cold deformation in accordance with VdTÜV-Wb 418 and NGS 1606.
Heat treatment is carried out in the form of solution annealing (see under Heat treatment) or resistance annealing. Hot bending is carried out at 1100-950°C (2010-1740°F) and should be followed by solution annealing.
Applications
Due to its excellent corrosion properties, 2205 duplex steel is a highly suitable material for service in environments containing chlorides and hydrogen sulphide. The material is suitable for use in production tubing and flowlines for the extraction of oil and gas from sour wells, in refineries and in process solutions contaminated with chlorides.
The high strength of 2205 duplex steel makes the material an attractive alternative to the austenitic steels in structures subjected to heavy loads.
