The application for the patent was published on Oct. 31, under issue no. 44/2025.
According to the abstract released by the Intellectual Property India: "This non-oriented electromagnetic steel sheet contains, in mass %, C: 0.0100% or less, Si: 1.50-4.00%, sol. Al: 0.0001-1.00%, S: 0.0100% or less, N: 0.0100% or less, and one or more selected from the group consisting of Mn, Ni, and Cu: total of 2.50-5.00%. When, in mass%, Mn content is taken to be [Mn], the Ni content is taken to be [Ni], the Cu content is taken to be [Cu], the Si content is taken to be [Si], the sol. Al content is taken to be [sol. Al], and the P content is taken to be [P], the non-oriented electromagnetic steel sheet has a chemical composition that satisfies (2 [Mn] + 2.5 [Ni] + [Cu]) - ([Si] + 2 [sol. Al] + 4 [P]) = 1.50%. A411-011 is 15.0% or more, B50D is 1.70T or more, and W10D/400D is 10.4 W/kg or less."
