27、aling of cold rolled electrical alloyed steel sheet and strip delivered in the semi-processed state is the responsibility of the purchaser, attention is drawn to the importance of this treatment for the properties of the material. For this reason, the magnetic properties in Table 2 are given for a r
28、eference condition obtained by suitable heat treatment. To ensure that the properties in use are equivalent to those specified, it is important that the industrial treatment carried out by the purchaser is equivalent to that used to define the reference condition (see 7.1.1). 1 Scope This European S
29、tandard defines the grades of cold rolled electrical non-oriented alloyed1) steel sheet and strip delivered in the semi-processed condition, that is without final heat treatment, of 0,50 mm and 0,65 mm nominal thickness. It specifies general requirements, the magnetic properties, the geometric chara
30、cteristics and tolerances, technological characteristics as well as the inspection procedure. This European Standard applies to material intended for the construction of magnetic circuits. These magnetic materials correspond to clause C.21 of IEC 404-1. 2 Normative references This European Standard
31、incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to thi

In addition, for the puroses of this
37、 European Standard, the following definitions apply: 3.1 edge camber the greatest distance between one longitudinal edge of a length of strip and the line joining the two extremities of the measured length corresponding to this edge 3.2 flatness the property of a sheet or a length of strip which is
38、characterized by the wave factor i.e. the relation of the height of the wave to its length 3.3 residual curvature the permanent curvature in the direction of rolling present in the coil in the delivery condition 1) Alloyed steel is that steel the basic constituent of which is iron containing alloyin

40、0 2006, Uncontrolled Copy, (c) BSI EN 10165:1995 4 BSI 02-1999 4 Classification The grades covered by this European Standard are classified according to the value of maximum specific total loss in watts per kilogram at 1,5 T and according to the nominal thickness of the material (0,50 mm or 0,65 mm)
41、. 5 Designation 5.1 For the steel grades covered by this European Standard, the steel names are allocated in accordance with EN 10027-1; the steel numbers are allocated in accordance with EN 10027-2. 5.2 The steel name comprises the following in the order given: 1) the letter M for electrical steel;
42、 2) one hundred times the specified value of maximum specific total loss at 1,5 T and 50 Hz, in watts per kilogram and corresponding to the nominal product thickness; 3) one hundred times the nominal thickness of the material, in millimetres; 4) the characteristic letter E for alloyed electrical she
43、et or strip delivered in the semi-processed state. EXAMPLE: M520-65E for electrical alloyed steel sheet or strip with a maximum specific total loss at 1,5 T of 5,20 W/kg at 50 Hz and a nominal thickness of 0,65 mm supplied in the semi-processed state. 6 General requirements 6.1 Production process Th
44、e production process of the steel and its chemical composition are left to the discretion of the manufacturer. 6.2 Form of supply The material is supplied in bundles in the case of sheets and in coils in the case of strip. The mass of bundles of sheets or of coils shall be agreed at the time of orde
45、ring. The most usual values for internal diameter of coils are approximately 500 mm and 600 mm. The recommended value is approximately 500 mm. The external diameter shall be agreed at the time of ordering. Sheets which make up each bundle shall be stacked so that the side faces are substantially fla
46、t and approximately perpendicular to the top face. Strip shall be of constant width and wound in such a way that the edges are superimposed in a regular manner and that the side faces of the coil are substantially flat. Coils shall be sufficiently tightly wound in order that they do not collapse und
47、er their own weight. Strip can occasionally exhibit welds or interleaves resulting from the removal of defective zones, subject to prior agreement between the parties. If necessary, marking of welds or interleaves may be agreed at the time of ordering. For coils containing welds or interleaves, each
48、 part of the strip shall be of the same grade. The edges of parts welded together shall not be so much out of alignment as to affect the further processing of the material. 6.3 Delivery condition Material supplied with trimmed edges shall not have any burrs which will adversely affect its further ap
49、plication or use. As the result of the method of manufacture and delivery in the form of coils, material may, in the delivery condition, exhibit residual curvature in the rolling direction as well as certain internal stresses. Precautions shall be taken by the user to reduce or eliminate the effect of these factors on the application or use of the material. The material is usually supplied without an insulating coating. 6.4 Surface condition The surfaces shall be uniform and clean. Dispersed defects such as scratches, blisters, cracks
