Title: Norihiro Fujita: Innovator in Hot Pressing Technology
Introduction
Norihiro Fujita is a prominent inventor based in Tokai, Japan. He is known for his significant contributions to the field of materials engineering, particularly in the development of advanced hot pressing methods for steel sheets. His innovative approach has implications for various industries, including automotive manufacturing.
Latest Patents
Fujita holds a patent for a "Hot pressing method for high strength member using steel sheet and hot pressed parts." This method allows for the hot pressing of various types of steel sheets, including hot rolled, cold rolled, Al-based plated, and Zn-based plated sheets. The resulting hot pressed sheets can achieve a strength of at least about 1200 MPa while minimizing the risk of hydrogen embrittlement. The steel sheets may contain between about 0.05 to 0.5 wt % carbon and can be heated to temperatures exceeding the Ac1 temperature but not exceeding about 1100°C. The process also involves controlling the atmosphere during heating to contain no more than about 6 vol % hydrogen and a dew point of not more than about 10°C. This exemplary method is particularly useful for forming high strength parts for automobiles.
Career Highlights
Fujita is associated with Nippon Steel Corporation, a leading company in the steel industry. His work has contributed to advancements in steel processing techniques, enhancing the performance and safety of steel components used in various applications.
