Applications of Duplex Stainless Steel

Duplex Stainless Steel can be difficult to weld properly. The balance of properties is the key.

Duplex Stainless Steels have a microstructure that contains both ferrite and austenite. 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 cracking resistance than most austenitic alloys and greater toughness than ferritic alloys, especially at low temperatures.

RAM has the experience and knowledge to make sure each weld is always correct. Our extensive experience with reactive metals makes RAM an excellent choice for all your Duplex Stainless Steel requirements.

Cost Benefits of Duplex Stainless Steel May Make It a Good Choice for Your Project.

*Please Note: Final selection of material must be based on actual evaluation of the metal in the corrosive medium under study and is the responsibility of the end user. Temperature and concentration play an important factor in corrosion resistance.
