WORKING CONDITIONS / FABRICATION
Heat Treatment	Weldability	Machinability [100 = CF8M]	Patternmaker’s Shrinkage [%]
Solution Annealing	Excellent	–	2.3

APPLICATIONS/ENVIRONMENTS/DESIGN CONSIDERATIONS
Higher strength and corrosion resistance compared to 2205, especially in enviroments containing chlorides. Typical applications are Oil&Gas exploration and production, oil refining, seawater cooling, salt evaporation plants, desalination units, pulp and paper production, chemical processing, geothermal wells, desulphurisation units.
