Duplex Stainless Steels—Alloys for the 21st Century

Metals, 2021
Duplex stainless steels were first manufactured early in the 20th century, but it was the introduction in the 1970s of the argon-oxygen decarburisation (AOD) steel making process and the addition of nitrogen to these steels, that made the alloys stronger,

Weldability of Duplex Stainless Steel [PDF]

Materials and Manufacturing Processes, 2015
Duplex stainless steels (DSSs) have many advantages due to the unique structural combination of ferrite and austenite grains. The structural change of these materials is very complex during welding, and it deteriorates the functional properties. This research investigates different welding processes such as laser beam, resistance, tungsten inert gas ...
