Abstract

According to the present invention a high strength electrical steel sheet which is suitable as a material for a rotor for a high speed rotating motor can maintain high strength thereof steadily and has excellent magnetic properties can be produced. The high strength electrical steel sheet has a chemical composition containing in mass% 0.005% or less of C more than 3.5% and 4.5% or less of Si 0.01% to 0.10% inclusive of Mn 0.005% or less of Al 0.0010% to 0.0050% inclusive of Ca 0.0030% or less of S and 0.0030% or less of N wherein the Ca/S ratio is 0.80 or more and the remainder of the chemical composition is made up by Fe and unavoidable impurities. The high strength electrical steel sheet has a thickness of 0.40 mm or less contains a deformed structure of uncrystallized crystals in an amount of 10% to 70% inclusive and has tensile strength (TS) of 600 MPa or more and iron loss (W) of 30 W/kg or less.
