25、cope This European Standard defines the grades of steel sheet and strip with specified mechanical properties and magnetic permeability.

31、magnetic characteristics employed in this standard are given in IEC50 (121) and IEC50 (221). In addition, for the purpose of this European Standard, the following definitions apply. 3.1 flatness 3.1.1 flatness of a sheet the maximum height of any point of the sheet above a flat horizontal surface, t

32、he sheet resting freely on this surface 3.1.2 flatness of a strip the property of a length of strip which is characterized by the wave factor, i.e.by the relation of the height of the wave to its length 3.2 edge camber the greatest distance between one longitudinal edge of a length of strip and the

33、line joining the two ends of the measured section corresponding to this edge 4 Classification The grades covered by this standard are classified according to the minimum value of the0,2% proof stress in newtons per square millimetre 1)and according to the minimum value of the magnetic flux density f

34、or a magnetic field strength of15kA/m. 1) 1N/mm 2 =1MPaEN10265:1995 4 BSI 06-1999 The grades are classified in two groups according to their manufacturing process: hot-rolled materials and cold-rolled materials. 5 Designation 5.1 The conventional designation 2)of the different grades comprises the f

35、ollowing in the order given: 1) the specified minimum value of the0,2% proof stress of the material, in newtons per square millimetre; 2) one hundred times the nominal thickness of the product, in millimetres; 3) the characteristic letters: TF for cold-rolled material, and TG for hot-rolled material

36、; 4) one hundred times the specified minimum value of the magnetic flux density in teslas for a magnetic field strength of15kA/m. Example 350 100 TF181 for a cold-rolled material with a minimum magnetic flux density of1,81 T for a magnetic field strength of15kA/m, a specified minimum0,2% proof stres

37、s of350N/mm 2 , and a nominal thickness of1,0mm. 5.2 The numerical designation is in accordance with EN10027-2. 6 General requirements 6.1 Production process The production process of the steel and its chemical composition are left to the discretion of the manufacturer. 6.2 Form of supply The materi

38、al is supplied in bundles in the case of sheets and in coils in the case of strip. The sheets which make up each bundle shall be stacked so that their edges are superimposed in a regular manner. The strip shall be of constant width, and wound in such a way that the edges are superimposed in a regula

39、r manner and the end faces of the coil are substantially flat. The coils shall be sufficiently tightly wound that they do not collapse under their own weight. The strips may occasionally exhibit welds or interleaves resulting from the junction made after removal of the defective zones or from the jo

40、ining of several lengths to obtain the sizes of the coils required by the user. In the absence of prior agreement, the form of repair is left to the discretion of the manufacturer. The welds or interleaves shall be marked. For coils containing repair welds or interleaves, each part of the strip shal

41、l be of the same quality. The edges of the parts welded together shall not be so much out of alignment that their ability to be worked is affected. Material supplied in sheets shall not contain any welds. The mass of bundles of sheet or coils shall be agreed at the time of ordering. 6.3 Delivery con

42、dition The materials are normally supplied without an insulating coating. By agreement, the materials can be supplied with an insulating coating on one or both sides. In this case, the nature of the insulating coating, its properties and their verification shall be subject to special agreement when

43、ordering. Materials produced by hot-rolling are normally supplied with an oxide scale coating unless they have been ordered pickled. By agreement, the products can be supplied lightly coated with oil. Coils supplied with trimmed edges and sheets shall not contain burrs or cutting distortions which a

44、re prejudicial to the method of working of the material. 2) The designation of steel products specified in this standard is not included in EN10027-1; therefore, the designations used are those in IEC404-8-5.EN10265:1995 BSI 06-1999 5 6.4 Surface condition Unless indicated otherwise, the surfaces sh

45、all be smooth and clean, free from grease and rust as well as all other defects such as scratches, blisters, cracks etc. (see clause10). However, dispersed defects can be tolerated if they are within the tolerance limits for thickness and if they are not detrimental to the correct use of the finishe

46、d product. 6.5 Suitability for cutting The material shall be capable of being cut or punched without causing premature wear of tools; it shall be able to be cut at any point and in the usual shapes thus ensuring precise working with appropriate tools in good condition. If there are special requireme

47、nts for an acceptance test for punching or shearing, these shall be established between the supplier and the purchaser. 6.6 Suitability for welding The suitability for welding of the material can be the subject of agreement when ordering. 7 Technical requirements 7.1 Mechanical properties The minimu

48、m specified values of the0,2% proof stress (R p0,2 ), of the tensile strength (R m ) and of the percentage elongation after fracture (A 80mm ) are given in Table 1 and Table 2. 7.2 Magnetic properties The minimum specified values for the magnetic flux density for magnetic field strengths of5000A/m a

49、nd15000A/m are given in Table 1 and Table 2. 7.3 Geometrical characteristics and tolerances 7.3.1 Thickness The recommended nominal thicknesses are the following: hot-rolled materials:1,6mm,1,8mm,2,0mm,2,5mm,3,0 mm,3,2mm and4,5mm; cold-rolled materials:0,5mm,1,0mm,1,6mm,1,8mm, and2,0 mm. For thickness tolerance, a distinction is made between: the variation in nominal thickness within the same unit of acceptance; the variation in thickness of a sheet or in a length of strip in a direction parallel to the directio
