High Nitrogen Steels And Stainless Steels

Basic research and new manufacturing methods have led to high nitrogen steels (HNS), a promising new group of materials for use in advanced applications in mechanical and chemical engineering. The book deals with the atomic structure, constitution, properties, manufacturing and application of martensitic, austenitic, duplex and dualphase steels of superior strength and corrosion resistance. Combining metallurgy and engineering aspects. It gives a detailed overview and presents new results on HNS. The book is intended for scientists as well as technologists, who will find stimulating information.

This book describes the details of the research and development of nickel-saving high nitrogen austenitic stainless steel and high nitrogen steel (HNS) with excellent corrosion resistance in the sea. This resistance was realized by using nitrogen (N), one of the ubiquitous elements, as an alloying element. By using N it is possible to save nickel (Ni), a national strategic substance in Japan, to be partially reduced or to be totally free. Not only basic information about low nickel HNS but also its promising application to bipolar plates of solid polymer fuel cells are provided. Reduction of Ni ions in the cell environment can be expected to extend the life of the fuel cell. Furthermore, there is discussion of the serendipitous application and impact of nickel-free HNS in the field of biomaterials as an anti-nickel allergy material, leading to its development for coronary stents. The book includes an explanation of how to develop extremely high corrosion-resistance steel by controlling its level of oxygen. For researchers and engineers involved in the development and evaluation of corrosion-resistant materials in particular, this book is extremely helpful for understanding the details of the development of those materials.

These proceedings contain the papers presented at two conferences held at ASM International's Materials Week DEGREES87 and Materials Week DEGREES92 respectively. Most of the 1987 papers deal with the properties of various high-manganese steels for specific use: valve steels, free-machining steels,

High-nitrogen steels (HNS) are finding increased application in energy production, transportation, pulp and paper, oil and gas and chemical process industries, due to their outstanding mechanical properties as well as their corrosion/oxidation and wear resistance. The aim of this conference was to bring together experts from end-users (engineering and manufacturing companies), and participants from steel producers and research organizations, in order to exchange experience, scientific data and technical information regarding high-nitrogen steels.
