Some stainless steels are called «duplex» because they have a twophase microstructure consisting of grains of ferrite and austenite. Melt duplex stainless steel solidifies from the liquid phase to a completely ferritic structure. When the material is cooled to room temperature, about half of the ferritic grains transformed into austenitic grains («Islands»). The result is a microstructure of approximately 50% austenite and 50% ferrite. Duplex stainless steels have a two phase microstructure of austenite and ferrite grains. This provides the following advantages:
- Strength: duplex stainless steels are about twice as strong as regular austenitic or ferritic stainless steels;
- The hardness combined with ductility: duplex stainless steels have significantly better toughness and ductility than ferritic stamps; however, they do not reach the values of austenitic grades.
- Corrosion resistance: duplex grades have a range of corrosion resistance, similar to the range for austenitic stainless steels;
- The stress corrosion cracking resistance: duplex stainless steels show very good stress corrosion cracking resistance.
Brand duplex stainless steels
- SAF 2707 HD — a super-duplex alloy. High resistance to chloride corrosion, combined with high mechanical strength. especially suitable for use in aggressive acidic chloride environments;
- SAF 3207 HD is the alloy intended for operation in conditions of high corrosion, which requires also a very high mechanical strength. This makes the brand ideal for use in deep oil and gas wells;
- SAF 2507 alloy has high corrosion resistance in environment containing chloride, including sea water. Stand in an organic acid;
- SAF 2205 alloy has excellent corrosion resistance in most environments compared to a standard austenitic stainless steel ASTM 316L and twice the mechanical strength;
- Sanmac 2205 is the alloy possesses improved machinability. Provides excellent and stable mechanical properties for increased cutting speeds, reduce tool wear and the time of its installation.
