DIN EN 10111:2008-06 EN 10111:2008 (E) 4 1 Scope This European Standard specifies the grades of continuously hot rolled low carbon steel sheet and strip (in coils) for cold forming. Depending on its actual width, strip is classified as: ho
22、t rolled wide strip if its width is greater than or equal to 600 mm; hot rolled slit wide strip if its width is less than 600 mm. For each grade, it specifies the chemical composition and the mechanical properties. This European Standard is applicable to products of thickness not less than 1,0 mm an
23、d not exceeding 11 mm. This European Standard is not applicable to products covered by other standards, such as: hot rolled products of non-alloy structural steels for general use (see EN 10025 all parts); steel sheet for pressure purposes (see EN 10028 all parts); steel sheet for welded gas cylinde
24、rs (see EN 10120); quenched and tempered steels (see EN 10083-1 and EN 10083-2). 2 Normative references The following referenced documents are indispensable for the application of this document.

28、 4 Classification and designation 4.1 Classification The choice of steel grade and product type is left to the purchaser. For this choice, the purchaser may be advised by the manufacturer, but without any liability on the part of the latter, unless agreed at the time of enquiry and order. Hot rolled
29、 products are classified into four grades DD11, DD12, DD13 and DD14 defined by chemical composition, mechanical and forming characteristics (see Table 1). 4.2 Designation 4.2.1 The steel names are in compliance with EN 10027-1; the steel numbers, with EN 10027-2. 4.2.2 Products conforming to this Eu
30、ropean Standard shall be designated, in order, in the following way: a) product designation (e.g. “strip”, “sheet” or “slit strip cut longitudinally”) in line with EN 10079; b) number of this European Standard (EN 10111); c) symbolic or numerical designation of the steel (see Table 1). EXAMPLE Strip
31、 EN 10111 DD13 or Strip EN 10111 1.0335 5 Requirements 5.1 Steelmaking and manufacturing processes Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing processes are left to the discretion of the manufacturer. The purchaser shall be informed of these processes
32、if he specifies it. 5.2 Deoxidation For grade DD11 the method of deoxidation shall be at the manufacturers discretion. Grades DD12, DD13 and DD14 shall be fully killed. 5.3 Chemical composition Table 1 gives the permissible chemical composition limits in the cast. 5.4 Delivery conditions 5.4.1 The p
33、roducts shall usually be delivered with their surface as rolled. By agreement at the time of enquiry and order, the products may be delivered with descaled surface. When they are delivered as rolled, they are covered with a thin layer of scale of variable coloration. The products may be supplied wit
34、h a light skin-pass, either at the manufacturers discretion or by agreement at the time of enquiry and order. DIN EN 10111:2008-06 EN 10111:2008 (E) 6 5.4.2 The descaled products are usually delivered oiled. In this case, both surfaces are preserved by a layer of neutral non-drying oil, free of impu
35、rities, and uniformly spread in such a way that under normal conditions of packaging, transportation, handling and storage the products will show no corrosion for up to three months from the date on which the products are made available. The date of availability shall be notified to the purchaser wi
36、th reasonable prior notice compatible with the validity of corrosion resistance. The layer of oil shall be capable of being removed by alkaline solutions or usual solvents. The choice of protective oils may be subject to special agreement at the time of enquiry and order. If the conditions of transp
37、ortation or storage are such that special protection against corrosion is required, the purchaser shall inform the manufacturer at the time of enquiry and order. If the purchaser does not require the surfaces to be oiled, this shall be clearly indicated at the time of enquiry and order. NOTE If the
38、order is for unoiled products, the manufacturer is not responsible for the risk of corrosion. The purchaser is also advised that there is a greater risk of the appearance of light scratches during handling, transportation and putting into application. 5.4.3 Descaled products may be supplied with tri
39、mmed edges upon agreement at the time of enquiry and order (designation GK following EN 10051). 5.5 Mechanical properties Table 1 gives the basic mechanical properties valid for the four grades. They correspond to the increasing formability in the order DD11 to DD14. The characteristics indicated in
40、 Table 1 are valid for the period specified in the same Table 1, from the date on which the products are made available. The date of availability shall be notified to the purchaser with reasonable prior notice compatible with the validity of the mechanical properties. Subject to special agreement, t
41、he products may be supplied with special suitability for the production of a specific part. In this case, a maximum rejection percentage may be set by mutual agreement and acceptance on the basis of mechanical properties does not apply. 5.6 Surface characteristics The sheets shall be free of slivers
42、, blow holes, seams, cracks or scratches which would adversely affect their use. Pores, small pits, small marks, small scratches, kinks from pay-off reels and a slight coloration are permitted. The defects shall not be of such an extent that they might run the risk of causing failure or damage to to
43、oling or welding difficulties when in use. The surface quality of the unwound coil is assessed as for sheets. However, the percentage of surface defects is generally greater than when supplied in sheets. The maximum percentage of permissible rejections shall be fixed by special agreement at the time
44、 of enquiry and order. 5.7 Suitability for surface coating The products may be intended for metallic coating by the hot dipping or electrodeposition and/or organic or other coatings. When such a coating is required, it shall be specified at the time of enquiry and order. DIN EN 10111:2008-06 EN 1011
45、1:2008 (E) 7 5.8 Weldability The products are suitable for standard welding processes. However, the welding process and possible specific requirements of the resulting welded component should be specified at the time of enquiry and order, e.g. gas welding, structural safety requirements. For non-des
46、caled products, the welding process shall take into account the presence of a layer of scale. 5.9 Tolerances on dimensions and shape The tolerances on dimensions and shape are given in EN 10051 DIN EN 10111:2008-06 EN 10111:2008 (E) 8 Table 1 Characteristics aMechanical properties cLadle analysis ch
