Thin magnetic steel strip for use atmedium frequencies
|Publication Date:||20 March 2015|
|ICS Code (Magnetic materials):||29.030|
This Standard defines the grades of thin non-oriented magnetic steel strip for use at medium frequencies in nominal thicknesses of 0.05 mm, 0.10 mm, 0.15 mm and 0.20 mm (hereafter referred to as "thin non-oriented magnetic steel strip"), and of thin oriented magnetic steel strip for use at medium frequencies in nominal thicknesses of 0.05 mm, 0.10 mm and 0.15 mm (hereafter referred to as "thin grain-oriented magnetic steel strip"). It gives general requirements, magnetic properties, geometric characteristics, tolerances, technological characteristics, as well as inspection procedures.
This Standard applies to thin non-oriented magnetic steel strip and thin grainoriented magnetic steel strip (hereafter simply referred to as "steel strip") supplied in the fully annealed condition in coils and intended for the construction of magnetic circuits used for frequencies of 100 Hz to 20 kHz.
