Title: Innovations by Hideki Tanaka

Introduction

Hideki Tanaka is a notable inventor based in Shunan, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced stainless steels. With a total of 2 patents, his work focuses on enhancing machinability and workability in stainless steel products.

Latest Patents

Tanaka's latest patents include innovations in ferritic and martensitic stainless steels that excel in machinability. These stainless steels feature a unique structure where Cu-enriched particles, with a concentration of carbon not less than 0.1 mass % or concentrations of tin and/or indium not less than 10 mass %, are dispersed within a matrix. The precipitation and dispersion of these Cu-enriched particles are achieved by aging the stainless steel at temperatures between 500–900°C for at least one hour after the hot-rolling step. The ferritic stainless steel composition includes 0.01–1.0% carbon, silicon up to 1.0%, manganese up to 1.0%, 15–30% chromium, nickel up to 6.0%, and 0.5–6.0% copper. The martensitic stainless steel contains 0.01–0.5% carbon, silicon up to 1.0%, manganese up to 1.0%, 10–15% chromium, nickel up to 6.0%, and 0.5–6.0% copper. This innovative approach allows for machining without harmful influences on workability, corrosion resistance, and environmental impact.
