MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090085 A) filed by Jfe Steel Corporation on July 24, 2026, for Grain-Oriented Electromagnetic Steel Sheet And Method For Manufacturing Same.
Inventors include Shingaki Yukihiro; Shimoyama Yusuke; and Kokubu Akinori.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Provided is a grain-oriented electromagnetic steel sheet having stably exceptional magnetic properties over the entire length of a coil in production of a grain-oriented electromagnetic steel sheet using an inhibitor-less method. This grain-oriented electromagnetic steel sheet has a component composition comprising, in mass%, 2.0- 4.5% of Si, 0.01-0.5% of Mn, less than 50 ppm of each of Se, Te and O, less than 30 ppm of S, at least 2 ppm and less than 30 ppm of acid-soluble Al, and at least 5 ppm to less than 80 ppm of Ga, the balance being iron and unavoidable impurities, wherein B8 in a rolling direction is 1.900 T or greater, and the hysteresis loss Whys at B = 1.7 T satisfies relationship (1). Relationship 1: Whys = -2.5 × B8 + 5.15
