This document specifies cold-rolled electrical non-oriented non-alloy1) or alloy2) 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.
1) Non-alloy steel is that steel the basic constituent of which is iron containing alloying elements in amounts smaller than the limiting values fixed by EN 10020.
2) Alloy steel is that steel the basic constituent of which is iron containing alloying elements in amounts equal to or greater than the limiting values fixed by EN 10020.
