Introduction

Yukio Tsuda is a notable inventor based in Tokai, Japan. He has made significant contributions to the field of steel production, particularly in developing high-strength steel and non-oriented magnetic steel. With a total of 2 patents, his work has had a considerable impact on the industry.

Latest Patents

One of Tsuda's latest patents is a method for producing high-strength steel with improved weldability. This innovative steel has a tensile strength of 80 kgf/mm² or more and is produced through one-line quenching or on-line quenching and tempering. The resulting steel exhibits excellent low-temperature toughness and weldability, eliminating the need for high-temperature preheating before welding. The composition of this steel includes C=0.04% to 0.11%, Si ≤ 1.0%, Mn=0.5% to 2.00%, Mo=0.10% to 1.0%, Nb=0.005% to 0.05%, B=0.0009% to 0.0012%, Al ≤ 0.1%, and N ≤ 0.0060%.

Another significant patent by Tsuda is a method for producing non-oriented magnetic steel heavy plates with high magnetic properties in low magnetic fields. This method involves hot-rolling high-purity steel, adjusting the crystal grain size, and conducting dehydrogenation treatment to impart a uniform ferrite grain diameter to the steel.
