In addition, for the purpose of this European Standard. the following dehtions apply Page 4 EN 10265:1995 3.1 flatness 3.1.1 flatness of a sheet: The maximum height of any point of the sheet above a flat horizontal surface, the sheet resting freely on this surfa

23、ce. 3.1.2 flatness of a strip: The property of a length of strip which is characterized by the wave factor, .e., by the relation of the height of the wave to its length. 3.2 edge camber: The greatest distaace between one iongitudinai edge of a length of strip and the line joining the two ends of the

24、 measured section corresponding to this edge. 4 Classification The grades covered by this standard are classified according to the minimum value of the 0.2 % proof stress in newtons per square millimetere” and according to the minimum value of the magnetic flux density for a magnetic field strength

25、of 15 Wm. The grades are classified in hvo groups according to their manufactuM process: hot-roiled materials and cold-rolled matenals. 5 Designation 5.1 order given: The conventional desipation” of the different grades comprises the following in the 1) the specified minimum value of the 0,2 % proof

26、 stress of the material, in newtons per square millimetre; 2) one hundred times the nod thickness of the product, in millimetres; 3) one hundred times the specified minimum value of the magnetic flux density in teslas for a magetic field strength of 15 Wm. EXAMPLE: 350-100 - TF 18 1 for a cold-roile

27、d material with a minimum magnetic flux density of 1,81 T for a magnetic field strength of I5 Wm, a specified minimum 0,2 % proof stress of 350 N/mm, and a nominal thickness of 1,0 mm. 5.2 The numerical designation is in accordance with EN 10027-2. ” I N/mm= I MPa The designation of steel products s

28、pecified in this standard is not included in EN 10027-1. therefore. the designations used are those in iEC 404-8-5 Page 5 EN 10265:1995 6 General requirements 6.1 Production process The production process of the steel and its chemical composition are lefi to the discretion of the manufacturer. 6.2 F

29、orm of supply The material 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

30、superimposed in a regular manner and the end fces of the coil are substantially flat. The coils shall be sufficiently tightly wound that they do not coiiapse under their own weight. The strips may occasionally exhibit welds or interleaves resulting from the junmon made after removal of the defective

31、 zones or from the joinins 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 contaming repair welds or interleaves. each pa

32、rt of the strip shall be of the same qualin. 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 ordehg

33、6.3 Delivery condition The matenals 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 verincation shall be subject to special a

34、greement when ordering. Materiais 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 xith oil. Coils supplied with tnmmed edges and sheets shall not contain bum or cutting distorti

35、ons which are prejudicial to the method of workmg of the material. 6.4 Surface condition Unless indicated othenvise. the surfaces shall be smooth and clean, free from grease and rust as iveIl s ail other defects such as scratches. blisters. cracks etc. (see clause IO). However, Page 6 EN 10265:1995

36、dispersed defects can be tolerated if they are withui the tolerance limits for thickness and if they are not detrimental to the correct use of the finished product. 6.5 Suitability for cutting The material shall be capable of being cut or punched without causing premaure wear of tools; it shall be a

37、ble to be cut at any point and in the usual shapes thus ensuring precise working with appropriate tools in gd condition. If there are special requirements for an acceptance test for punching or shearing, these shall be established between the supplier and the purchaser. 6.6 Suitability for weldmg Th

38、e suitability for welding of the material can be the subject of agreement when ordering. 7 Technical requirements 7.1 Mechanical properties The minimum specified values of the 0,2 % proof stress (Rp,2), of the tensile strength (R,) and of the percentage elongation after fiachire (Ash) are given in T

40、d materials: 1,6 mm, 1.8 mm, 2.0 mm, 2,j mm, 3.0 nun, 3,2 mm and 4,j mm; - cold-rolled materials: 0,5 mm, 1,O mm. 1,6 mm, 1,8 mm, and 2,O mm. For thickness tolerance. a distinction is made behveen: - the variation in nod thickness wivithui the same unit of acceptance; - the variation in thickness of

41、 a sheet or in a ien of strip in a direction pdel to the direction of roiling; - the variation in thickness of a sheet or in a length of strip in a direction perpendicular to the direction of roiling. This tolerance applies only to material with a width greater than 15Omm. 7.3.1.1 acceptance is depe
