Title: Keiji Hattori: Innovator in Spring Steel Technology

Introduction

Keiji Hattori is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of spring steel technology, holding two patents that showcase his innovative approach to material science.

Latest Patents

Hattori's latest patents include a unique steel material for colored springs. This steel material features a metallic deposit on its surface, which contains copper, zinc, and chromium. During the annealing process, the copper and zinc diffuse to create a gold color tone, while the chromium oxidizes to produce a dark gray color tone. The combination of these tones results in a beautiful black color that distinguishes it from standard springs. Additionally, he developed a method for facilitating the distinction between different spring steel products. This method improves surface appearance and corrosion resistance by plating the surface of various spring steel products before forming them. The plating involves alternate layers of copper and zinc or nickel, copper, and zinc, tailored to the size and material of the steel products. This innovation prevents mixing and erroneous assembly of different spring steel products.
