New electrical steel, which is characterized by improving the punching properties of steel, but also with Ca. The component percentages by weight: P0.12~0.35%; Mn0.25~0.7%; Si0.2~0.9%; Al0.004~0.5%; Ca0.002~0.01%; the rest being Fe (1980.7.15 application, Certificate of Invention № 908909 [8] ~ *). New alloy steel, which is characterized by adding V, N and Ca to improve the wear resistance and hardness of steel. The composition comprises the following components in percentage by weight: C0.7 to 1.5 percent, Mn5.4 to 8.0 percent, Si0.2 to 2.0 percent, V0.5 to 3.5 percent, N0.01 to 0.06 percent, Ca0.01 percent to 0.06 percent, Fe Balance (1980,6,26 application, the invention certificate № 908910 [8] ~ *). New alloy steel, in order to improve its low temperature (to -70 ℃) of impact toughness and plasticity without reducing the strength of the steel plus Co. The weight percentage of the component is as follows: C0.05-0.15%; Mn18-22%; V0.3-0.5%; Co0.4-0.8%; Fe balance (Declaration of January 7, 1980, invention certificate No. 908911 [8] ).
