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.
