41、 steel and its chemical composition are left to the discretion of the manufacturer. 6.2 Form of supply The material is supplied in coils in the case of strip and bundles in the case of sheets. The mass of coils or bundles of sheets shall be agreed at the time of enquiry and order. The recommended va
42、lue for the internal diameter of coils is approximately 508 mm. Strip shall be of constant width and wound in such a manner 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 so that they do not co
43、llapse under their own weight. Strip may exhibit welds resulting from the removal of defective zones if agreed at the time of enquiry and order. If necessary the marking of welds may be agreed at the time of enquiry and order. For coils containing welds, each part of the strip shall be of the same g
44、rade. The edges of parts welded together shall not be so much out of alignment as to affect the further processing of the material. Sheets which make up each bundle shall be stacked so that the side faces are substantially flat and approximately perpendicular to the top face. 6.3 Delivery condition
45、Cold rolled grain oriented electrical steel is usually supplied with an insulating coating on both sides. This coating generally consists of an EC-5-G coating on an EC-2 coating in accordance with EN 103421). 6.4 Surface condition The surfaces shall be smooth and clean, free from grease and rust 2).
46、 Dispersed defects such as scratches, blisters, cracks, etc., are permitted if they are within the limits of the tolerances on thickness and if they are not detrimental to the correct use of the supplied material. The insulation coating present on the surface of the material shall be sufficiently ad
47、herent so that it does not become detached during cutting operations or heat treatment under conditions specified by the supplier. If the product is to be immersed in a fluid, an agreement, initiated by the purchaser, should be reached to ensure compatibility between the fluid and the coating. 6.5 S
48、uitability for cutting The material shall be suitable for cutting accurately into the usual shapes at any point when appropriate cutting tools are used. 1)Other types of coating exist which are used only when particularly specified. 2)Not to be confused with some colouration of the insulating coatin
