Title: Fumio Murase: Innovator in Martensitic Steel Technology
Introduction
Fumio Murase is a distinguished inventor based in Aichi, Japan. He has made significant contributions to the field of materials science, particularly in the development of high chromium martensite steel. With a total of 3 patents to his name, Murase's work has had a profound impact on the industry.
Latest Patents
Murase's latest patents include a method of manufacturing high chromium martensite steel pipe that boasts excellent pitting resistance. This innovative method involves forming a steel pipe with specific compositions, including C: about 0.03 wt % or less, Si: about 0.5 wt % or less, Mn: about 0.5-3.0 wt %, Cr: about 10.0-14.0 wt %, Ni: about 0.2-2.0 wt %, Cu: about 0.2-1.0 wt %, and N: about 0.03 wt % or less, with the balance being Fe and incidental impurities. The pipe undergoes a quenching process after austenitizing at a temperature substantially equal to an A.sub.C3 point or higher, followed by annealing in a temperature range from about 550°C or higher to a temperature lower than an A.sub.C1 point. Additionally, he has developed martensitic steel for line pipes that exhibit excellent corrosion resistance and weldability.
