摘要:
A non-oriented electrical steel sheet contains: C: not less than 0.003 mass% nor more than 0.05 mass%; N: not less than 0.001 mass% nor more than 0.01 mass%; and Si: not less than 2.8 mass% nor more than 3.5 mass%. The non-oriented electrical steel sheet further contains at least one kind selected from a group consisting of Ni: 4.0 mass% or less and Mn: 2.0 mass% or less, in a total amount of 0.5 mass% or more, and further contains Ti, a value R Ti being not less than 1 nor more than 10, the value R Ti being expressed by [Ti]/(4x([C]+[N])) when a Ti content is expressed as [Ti] mass%, a C content is expressed as [C] mass%, and an N content is expressed as [N] mass%. An Al content is 3.0 mass% or less, and a P content is 0.2 mass% or less.
