Latest Patents
Koichi Akutsu 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, not more than 0.90% of silicon, 0.30-0.80% of manganese, 0.70-1.60% of chromium, 0.40-0.70% of molybdenum, with the remainder being substantially iron. 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, nitrogen, or boron, as well as third components like niobium or vanadium, and fourth components including aluminum, titanium, or zirconium in specified amounts.
