Tohoku University Technology: Iron alloy that is lighter and stronger than stainless steel: T05-117
Iron alloy with specific gravity less than 7, 0.2% proof stress more than 1000 MPa, and tensile stress more than 1000 MPa
Although stainless steel is an industrially important iron alloy, its specific strength is inferior to that of other metals because of its large specific gravity. An iron alloy having low specific gravity and high strength is required for the transport equipment. The present invention provides high strength iron alloy having the maximum 0.2% proof stress and the tensile stress more than 1000 MPa while having the specific gravity less than 7.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
