摘要（英）：

The invention discloses low alloy steel with the high electromagnetic property and the high strength and a production technology and application thereof. Chemical components of the steel material comprise, by weight, 0.01%-0.03% of C, 0.10%-0.20% of Si, 0.60%-0.90% of Mn, 0.003%-0.013% of Al, 0.010%-0.030% of Ti, smaller than or equal to 0.10% of Cr, Cu and Ni, smaller than or equal to 0.015% of Sand P and the balance Fe. According to the low alloy steel, the coercive force Hc (A/m) is smaller than or equal to 72, the maximum permeability mum (H/m) is larger than or equal to 0.0088, the tensile strength Rm (MPa) is higher than or equal to 350, the yield strength Rel (MPa) is higher than or equal to 210, the electromagnetic property is equal to that of electromagnetic pure iron, and the strength is two times that of the electromagnetic pure iron. A prepared continuously-cast blank is subjected to continuous casting, and the steel with the high electromagnetic property and strength requirements is obtained and widely applied to claw poles of electric generators in the industries of automobiles and engineering machinery.
