Nickel-saving Type High Nitrogen Austenitic Stainless Steel (eBook)

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.

Dr. Yasuyuki KATADA received his PhD from Osaka University in 1980. After working as a research associate at Osaka University during 1979-1981, he moved to NRIM (National Research Institute for Metals) of the Science and Technology Agency. NRIM was reorganized as National Institute for Materials Science (NIMS) in 2001. During his 30-year research life in NIMS, he engaged in nuclear safety research, development of corrosion resistant metallic materials in the Ultra Steel Project and the development of biomaterials. He has reported 67 articles and has published several books including metallic biomaterials so far. He won the Academic Contribution Award 'The Mishima Prize' from the Iron and Steel Institute of Japan in 2003, and the New Technology Award from Japan Society of Mechanical Engineers in 2010. He retired from NIMS in 2010. He was appointed as an honorary researcher of NIMS in 2018.
