Latest Patents
Hata's patent, titled "Process for manufacturing high-strength parts of an automobile," outlines a unique method for creating steel with specific chemical compositions. The steel contains varying percentages of carbon, silicon, manganese, aluminum, copper, nickel, niobium, and calcium, with iron making up the balance. The process involves heating the steel to temperatures between 1100°C and 1250°C, followed by hot rolling and coiling at temperatures of 350°C to 500°C. The resulting hot-rolled steel sheet achieves a tensile strength not exceeding 65 kgf/mm², which is then cold worked to establish a working strain of at least 15%. Finally, the cold-worked product is heated to yield a part with a tensile strength of at least 80 kgf/mm², particularly beneficial for automatic transmission systems in automobiles.
