scope:

This document specifies cold-rolled electrical non-oriented non-alloy or alloy steel sheet and strip delivered in nominal thicknesses of 0,50 mm and 0,65 mm in the semi-processed condition, that is without final heat treatment; in particular, it specifies general requirements, magnetic properties, geometric characteristics and tolerances and technological characteristics, as well as the inspection procedure. This document applies to material intended for the construction of magnetic circuits. These magnetic materials correspond respectively to subclauses C21 and B2 of IEC 60404-1:2000. This document has been prepared by merging EN 10126:1995 and EN 10165:1995, taking into consideration corresponding decisions of IEC/TC 68 on relevant IEC documents IEC 60404-8-2:1998 and IEC 60404-8 -3:1998 which are being merged at the same time. The merged document published as IEC 60404-8-3:2005 was the basis of this European Standard. The intention of this merging was to specify no longer non-alloy and alloy steel grades for cold rolled electrical steel sheet and strip, but to leave the type of steel open. Therefore, it has been decided to use a new letter "K" instead of previous used "D" or "E" for the designation of electrical steels specified in this European Standard.
