Superaustenitic Stainless Steels

This book provides an exhaustive overview of a class of materials with distinct mechanical and corrosion resistance properties: superaustenitic stainless steels. It strives to fill the gap in the literature on these materials by offering a comprehensive overview based on the author's experience in the metallurgical industry and by organizing information from the available literature. Topics are presented in a structured and detailed manner, accompanied by images and graphs created specifically for this book, including original material like optical micrographs Special attention is also given to cultural-historical aspects that are often overlooked but are critical for understanding the characteristics of the material. Superaustenitic stainless steels (SASSs) take the characteristics of austenitics to the extreme for maximum performance and feature a complex chemical composition of high Cr, Ni, Mo, and N content. The book is divided into four parts: an introduction to stainless steels, a chapter on the specific metallurgy of SASSs, a section on mechanical, physical, and corrosion resistance properties, and a chapter on production technologies, processing, and uses. It also includes extended appendices on the effects of alloying elements in steels and on the characteristics of the phases found in stainless steels. The book is addressed to a wide audience, from university students to professionals and consultants in the field who need literature support to innovate on materials and production processes.

Autorentext

Alessio Malandruccolo is an industrial consultant working in Italy and Europe. He gained experience in the steel industry working for a prestigious Italian company, specialized in the production of stainless steels and nickel alloys. At that time, he was involved in R&D, quality control and improvement, failure analysis, and revamping and design of new installations for production of new alloys. He has coordinated product development and industrialization projects for the Italian site of a German company operating in the sheet metal working field, with main focus on the home appliance industry. Subsequently, he started one of the Italian sites of a company operating in the field of mechanical design and engineering consulting. He received his Master degree in Materials Science and Engineering at the University of Trento. He developed part of his research experience and skills at the European Synchrotron Radiation Facility - ESRF (Grenoble, France) - and at the Diamond Light Source (Didcot, United Kingdom), focusing mainly on X-ray diffraction applied to inorganic materials characterization. Since shortly after graduation, he has been involved in academic teaching as teaching assistant in Materials Technology and Applied Chemistry at the University of Trento, and as lecturer and teaching assistant in Manufacturing Technology at the Free University of Bolzano. Since 2020, he has also been teaching at high schools on Manufacturing Technology and Applied Science and Technology. He has co-authored publications related to the processing of titanium alloys produced by additive manufacturing. Together with Stefano Gialanella, he is the author of the book Aerospace Alloys.
