Title: Yukio Ito: Innovator in Steel Technology
Introduction
Yukio Ito is a notable inventor based in Yokkaichi, Japan, recognized for his contributions to the field of steel technology. With a total of 5 patents to his name, he has made significant advancements that enhance the performance and cost-effectiveness of steel materials.
Latest Patents
One of his latest patents is for a corrosion-resistant spring steel. This innovative spring steel is of medium strength and offers sufficient corrosion resistance, prepared through simple procedures at a low cost. The alloy composition includes C 0.3-0.6%, Si 1.0-2.0%, Mn 0.1% to less than 0.5%, Cr 0.4-1.0%, V 0.1-0.3%, Ni more than 0.5% to 1.2%, Cu 0.1-0.3%, and the balance of Fe, with S at a maximum of 0.005% and [O] at a maximum of 0.0015%. The specific contents of S, Ni, Cr, Cu, and V are chosen to ensure an improved fatigue limit under corrosive environments compared to conventional steel.
Another significant patent involves a forging lubricant and a method for forming a lubricant coat on steel materials. This lubricant, composed of thermally melting resin mixed with inorganic lubricant, is sprayed onto the surface of steel materials to be forged. The process involves heating the steel surface before or after applying the lubricant, allowing the resin to melt and bond with the inorganic lubricant, resulting in a uniformly thick lubricant coat. This coat prevents burning during hot forging and contributes to reduced forging costs without compromising the forging environment.
