Stainless steel, termed as the ‘miracle metal’ is all around us in numerous applications ranging from everyday household items to sophisticated biomedical applications. Stainless steel is one of the fastest growing segments in metal industries. New developments and a wide range of research on stainless steel is taking place all around the world in order to obtain superior quality stainless steel and expand its applications to meet growing demands. Taking those facts into account, this book is compiles recent developments in the properties, applications and further processing of stainless steel and recent research trends. The book includes high-tech characterization techniques of stainless steel to address the decomposition behaviour; decomposition-induced transformation to the correlated property-microstructure; powder metallurgy to produce difficult-to-cast stainless steel components, depassivation/repassivation behaviour, various surface treatment processes as well as a wide range of machining techniques to address the need of machinability of stainless steel.
