When Duplex Stainless Steel is melted, it solidifies from the liquid phase to a completely ferritic structure. As the material cools, approximately half of it changes to an austenitic structure. The result is an alloy with a microstructure of roughly 50% austenite and 50% ferrite. Duplex alloys have higher strength and better stress corrosion ...
