3 F oreword JFE Steel, s electrical steel sheets have a long tradition dating back to 1931 when we started the production of hot-rolled magnetic steel sheets. Ever since, we have maintained the world's top-level track record through continuous quality improvements and the development of innovative products. Certified for compliance with the ISO9001 and ISO14001 standards, JFE Steel produces highquality, energy-saving and environmentally compatible electrical steel sheets for a wide range of customers. his catalog outlines the features and representative properties of various electrical steel sheets manufactured by JFE Steel. For detailed data and characteristic curves of each type of electrical steel sheet, please read the relevant separate catalog. We at JFE Steel are coitted to making continuous efforts so as to meet all requirements of our customers and ensure even greater customer satisfaction. We look forward to serving your current and future needs. 1

4 ypes and Applications Grain-Oriented Electrical Steel Sheets Non-Oriented Electrical Steel Sheets JFE G- JG JGH JGS JGSD JGSE JFE G- is so manufactured as to possess a well-aligned crystal orientation to the rolling direction. herefore, it has superior properties such as high permeability, low core loss and low magnetostriction. JGSD is core material with fine magnetic domains subdivided by grooves formed by electrolytic etching and is ideal with its low iron loss both in wound core and stacked core applications. JGSE is non-heat resistant magnetic domain-refined material suitable for stacked core applications. Used mainly for power transformers and distribution transformers as well as for large rotating machines, JG, JGH, JGS, JGSD and JGSE contribute greatly to improving the efficiency of machines and to reducing their weight. JFE N- JN JNE JNEH JNA JFE N- is so manufactured as to render magnetic properties almost uniform in any direction of the coil. Used mainly for medium and large rotating machines, and small transformers, JFE N- contributes to improving machine efficiency. JNE is a core material which can achieve low core loss and high permeability. JNEH is a core material which can achieve low core loss in the high frequency range. JNA is a core materal which can achieve low core loss and high permeability after stress relief annealing by customers. For applications such as electric household appliances, office equipment and stabilizers, JN, JNE, JNEH and JNA provide superior coatings, coupled with excellent thickness accuracy, to say nothing of superior magnetic properties. ypes Grain-Oriented Non-Oriented Applications JG JGH, JGS, JGSD, JGSE JN 210~400 JN 440~700 JN 800~1600 JNE 230~470 JNEH 1200~1500 JNA 300~500 Large Rotating Machines Medium Rotating Machines Rotating Machines Hermetical Motors General use A.C.

22 Stress-Relief Annealing Magnetic properties of electrical steel sheets are deteriorated by a mechanical strain caused by shearing, punching, bend-forming. Stress-relief annealing is performed to remove such strain and to restore the inherent good magnetic properties. Stress-relief annealing may vary according to the degree of fabrication and the type of annealing equipment. he following points call for attention: Heating and cooling rates Magnetic properties are not affected by heating or cooling rates as performed on an ordinary industrials scale. However, care must be taken so that no strain will remain in the material. Annealing temperature and holding time a. Grain-oriented Electrical steel sheets Optimum annealing temperature range is C. (1436 F F) Material must be maintained until heated up uniformly within this temperature range. Holding time varies depending upon the shape of core, the number of coils charged and the type of furnace. b. Non-oriented Electrical steel sheets Optimum temperature of the stress-relief annealing, when required, is C.(1328 F-1382 F) Prevention of carburization and oxidation Since carburization and an excessive oxidation will cause the deterioration of magnetic properties of the steel, the atmospheric gas must be carefully controlled and the gas must also have a low dew point. For the prevention of the carburization during annealing, organic compounds such as oil and grease remained on the coil surface during the fabrication must also be removed completely in advance. he use of material of low carbon content is recoended for the base and cover of the annealing furnace. 21

23 Surface Insulation JFE Steel offersthe following typesof coatingsfor surface insulation.he customers can select one that best meetstheir requirementsfor interlamination resistance, punchability, heat resistance, Freon resistance and other properties. he Characteristics of Insulating Coatings for JFE N-(0.5 thick) (1) Applied grades Items A, N (thin) J (thin) A, N (thick) D Notice JN, JNE, JNEH, JNA JN, JNA JN, JNE, JNEH, JNA JN, JNE, JNA A, N Coating Asto A, N coating, an organic resin isadded to inorganic coating. It has excellent punchability, corrosion resistivity and Freon resistance, with exceedingly high interlamination resistance shown in the case of the higher grades. Suited to large rotors, especially to motors for electric household applianceswhere good punchability isrequired. A and N Coating has no equivalent in the AISI standards.

In comparison with A,N coating, it has excellent heatresistancy due to the improvement of an organic resin itself. J coating has no equivalent in the AISI standards. Unless otherwise specified, A Coating will be applied and at the end of grade designation, type of surface insulation is indicated. Ex : 50JN600*A means 50JN600 appiled with A coating.
