It is wellknown that 6.5% Si steel has excellent soft magnetic properties, but high Si steel more than 4% Si are so brittle that it is impossible to manufacture thin gauge steel sheets using the conventional rolling process.
Using the siliconizing method, we have succeeded in developing the world's first non-oriented 6.5% Si steel sheets for commercial production in coil form, with a thickness range 0.1-0.5 mm.
The 6.5% Si steel sheets have no void and exhibit excellent soft magnetic properties, a high frequency core loss W10/400 of 9.9 W/kg for a thickness of 0.3mm. In addition, the product has good workability.
