The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
7、r body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec
8、trotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopt
9、ed by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of paten
10、t rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3573 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 12, Continuous mill flat rolled products. This fif th edition cancels and replaces the fourth edition ( ISO 3573:2008), which has

Hot-rolled steel sheet
12、is suitable for many applications where the presence of oxide or scale, or normal surface imperfections disclosed after removal of oxide or scale, are not objectionable. It is not suitable for applications where the surface is of prime importance. NOTE This International Standard does not cover stee
13、l sheet that is to be subjected to subsequent rerolling. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the lates
14、t edition of the reference document (including any amendments) applies. ISO 6892-1, Metallic materials Tensile testing Part 1: Method of test at room temperature ISO 16160, Hot-rolled steel sheet products Dimensional and shape tolerances 3 T erms an d definiti ons For the purposes of this document,
15、the following terms and definitions apply. 3.1 hot-rolled steel sheet product obtained by rolling heated steel through a continuous hot strip mill or another hot-rolling process that produces a coiled product to the required sheet thickness and tolerances 3.2 hot-rolled descaled steel sheet hot-roll
16、ed steel sheet from which oxide or scale has been removed, commonly by pickling in an acid solution or by mechanical means such as grit blasting Note 1 to entry: Some change in properties can result from descaling. Note 2 to entry: Descaling can also be performed by appropriate mechanical means. 3.3
17、 skin pass light cold-rolling of hot-rolled steel sheet or hot-rolled descaled steel Note 1 to entry: The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface cond
18、ition known as stretcher strain (Luders Lines) or fluting during the fabrication of finished parts. The skin pass also controls and improves flatness. Some increase in hardness and loss of ductility will result from skin passing. 3.4 mill edge normal side edge without any definite contour produced i

21、inclusive, and in widths of 600 mm and over, in coils and cut lengths. 4.2 Hot-reduced sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet. 5 Conditions of manufacture 5.1 Chemical composition The chemical composition (heat analysis) shall not exceed the values gi
22、ven in Tables 1 and 2. On request, a report of the heat analysis shall be made to the purchaser. Each of the elements listed in Table 2 shall be included in the report of the heat analysis. When the amount of copper, nickel, chromium or molybdenum present is less that 0,02 %, the analysis result may
23、 be reported as “ 0,02 %”. A verification analysis may be made by the purchaser to verify the specified analysis of the product and shall take into consideration any normal heterogeneity. Non-killed steels (such as rimmed or capped steels) are not technologically suited to product analysis. For kill
24、ed steels, the sampling method and deviation limits shall be agreed upon between the interested parties at the time of ordering. The product analysis tolerances are shown in Table 3. The processes used in making the steel and in manufacturing zinc-coated sheet are left to the discretion of the manuf
