Sanmac 2205
Sanmac®2205 is a duplex (austenitic-ferritic) stainless steel grade with excellent material
cleanliness, for highly demanding applications.
The grade is characterized by:
High:
– Mechanical strength – roughly twice the proof strength of standard austenitic stainless steels
– Resistance to stress corrosion cracking (SCC) in chloride-bearing environments
– Resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide
– Resistance to general corrosion, pitting and crevice corrosion
– Resistance to erosion corrosion and corrosion fatigue
Good:
– Hot-working properties
– Weldability

Aplications:
Due to its excellent corrosion properties, Sanmac®2205 is a highly suitable material for service in environments containing chlorides and hydrogen sulfide.
The material is suitable for use in flowlines for the extraction of oil and gas from sour wells, in refineries and
in-process solutions contaminated with chlorides. Sanmac®2205 is particularly suitable for chloride-bearing water or brackish water is used as a cooling medium.
The steel is also suitable for use in dilute sulphuric acid solutions and for the handling of organic acids, e.g. acetic acid and mixtures.
– The high strength of Sanmac®2205 makes the material an attractive alternative to austenitic steels in
structures subject to heavy loads.
– The good mechanical and corrosion properties make Sanmac®2205 an economical choice in many
applications by reducing the life cycle cost of the equipment.
