Title: Yui Kusuhara: Innovator in Low C-Cr-Mo Steel
Introduction
Yui Kusuhara is a notable inventor based in Okayama, Japan. She has made significant contributions to the field of materials science, particularly in the development of specialized steel alloys. Her innovative work focuses on enhancing the properties of steel used in demanding environments.
Latest Patents
Yui Kusuhara holds a patent for a novel low C-Cr-Mo steel that exhibits excellent weldability and high erosion-corrosion resistance under wet steam conditions. This steel composition includes, by weight, 0.02-0.14% of carbon (C), not more than 0.90% of silicon (Si), 0.30-0.80% of manganese (Mn), 0.70-1.60% of chromium (Cr), 0.40-0.70% of molybdenum (Mo), with the remainder being substantially iron (Fe). This innovative material is particularly suitable for fabricating components in feed-water heaters, especially in nuclear power generation plants, where it is subjected to wet steam conditions. The properties of this steel can be further enhanced by the addition of secondary components such as copper (Cu), nitrogen (N), or boron (B), as well as tertiary components like niobium (Nb) or vanadium (V), and quaternary components including aluminum (Al), titanium (Ti), or zirconium (Zr) in specified amounts.
