Book description
Duplex Stainless Steels (DSSs) are chromium-nickel-molybdenum-iron
alloys that are usually in proportions optimized for equalizing the
volume fractions of austenite and ferrite. Due to their
ferritic-austenitic microstructure, they possess a higher mechanical
strength and a better corrosion resistance than standard austenitic
steels. This type of steel is now increasing its application and market
field due to its very good properties and relatively low cost.
This book is a review of the most recent progress achieved in the
last 10 years on microstructure, corrosion resistance and mechanical
strength properties, as well as applications, due to the development
of new grades. Special attention will be given to fatigue and fracture
behavior and to proposed models to account for mechanical behavior.
Each subject will be developed in chapters written by experts
recognized around the international industrial and scientific communities.
The use of duplex stainless steels has grown rapidly in the last 10
years, particularly in the oil and gas industry, chemical tankers,
pulp and paper as well as the chemical industry. In all these
examples, topics like welding, corrosion resistance and mechanical
strength properties (mainly in the fatigue domain) are crucial.
Therefore, the update of welding and corrosion properties and the
introduction of topics like texture effects, fatigue and fracture
strength properties, and mechanical behavior modeling give this book
specific focus and character.
