17、rganization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been estab
18、lished 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat
19、ion. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 YO
20、 of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 6317 was prepared by T

23、 steel strip of commercial and drawing qualities 1 Scope 1.1 This International Standard applies to hot-rolled carbon steel strip of commercial and drawing qualities. NOTE Steel strip that is to be subjected to subsequent rerolling is not covered by this International Standard. Hot-rolled steel stri
24、p 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 surface is of prime importance. It is rolled on a narrow strip mill. 1.2 Commercial-qu
25、ality strip (HR1) is intended for general fabrication purposes where strip is used in the flat, or for bending, moderate forming and welding operations. It is commonly produced in the range of thicknesses 0,65 mm to 12 mm inclusive, and widths up to 600 mm exclusive, in coils and cut lengths. 1.3 Dr
26、awing-quality strip (HR2, HR3, HR4) is intended for drawing or severe forming, including welding. It is commonly produced in the range of thicknesses 0,65 mm to 12 mm inclusive, and widths up to 600 mm exclusive, in coils and cut lengths. Drawing-quality strip is furnished to all the requirements of
27、 this International Standard or, by agreement when ordered, to fabricate an identified part, in which case the mechanical properties in Table 2 do not apply. Specific drawing qualities are identified as follows: HR2 Drawing quality HR3 Deep-drawing quality HR4 Deep-drawing quality, aluminium-killed
28、2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, this publication do not apply. However, parties to agreements based
29、 on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain registers of currentl

33、 surface covered with oxide or scale resulting from the hot-rolling operation. 3.3 hot-roiled descaled steel strip hot-rolled steel strip from the surface of which oxide or scale has been removed, commonly by pickling in an acid solution NOTE loss of ductility may result from descaling. Descaling ma
34、y also be performed by mechanical means such as grit blasting. Some increase in hardness and some 3.4 skin pass a light cold rolling of the product NOTE 1 The purpose of skin passing is one or more of the following: a) to minimize the appearance of coil breaks, stretcher strains and fluting; b) to c
35、ontrol the shape; c) to obtain the required surface finish. NOTE 2 Some increase in hardness and some loss in ductility will result from skin passing. 3.5 mill edge a normal side edge produced without any definite contour in hot rolling NOTE 1 Mill edges may contain some irregularities such as crack
36、ed or torn edges or thin (feathered) edges. NOTE 2 A square mill edge can be produced by hot-edge rolling (with the corners not as square as a square-edge bar). 3.6 sheared edge a normal edge obtained by shearing, slitting or trimming a rnill-edge product NOTE Normal processing does not necessarily
37、provide a definite positioning of the slitting burr. I l 4 Conditions of manufacture 4.1 Steelmaking The processes used in making the steel and in manufacturing hot-rolled strip are left to the discretion of the manufacturer. On request, the purchaser shall be informed of the steelmaking process bei

39、ISO b317-ENGL 2000 4851903 0834743 781 IS0 6317:2000(E) 4.2 Chemical composition The chemical composition (heat analysis) shall be as agreed upon between the interested parties at the time of ordering. The ranges or limits shall be in accordance with the requirements of Table 1 for the designation s
40、pecified. Table 1 - Chemical composition (heat analysis) 4.3 Chemical analysis 4.3.1 Heat analysis A heat analysis of each heat of steel shall be made by the manufacturer to determine compliance with the requirements of Table 1. When requested at the time of ordering, this analysis shall be reported
41、 to the purchaser or his representative. 4.3.2 Product analysis A product analysis may be made by the purchaser to verify the specified analysis of the semi-finished or finished steel and shall take into consideration any normal heterogeneity. For killed steels, the sampling method and deviation lim
42、its shall be agreed upon between the manufacturer and purchaser at the time of ordering. 4.4 Weldability This product is normally suitable for welding if appropriate welding conditions are selected. For undescaled steel, it may be necessary to remove the scale or oxide, depending upon the welding me
43、thod. 4.5 Application It is desirable that hot-rolled steel strip be identified for fabrication by name of the part or by the intended application. Hot-rolled steel strip (HR1, HR2, HR3, HR4) may be produced to make an identified part within a properly established breakage allowance which shall be p
44、reviously agreed upon between the interested parties. In this case, part name, details of fabrication and special requirements such as freedom from stretcher strains or from fluting shall be specified and the mechanical properties in Table 2 do not apply. 4.6 Mechanical properties Except when ordere
45、d to make an identified part, as explained in 4.5, at the time that the steel is made available for shipment, the mechanical properties shall be as given in Table 2, when they are determined on test pieces obtained in accordance with the requirements of clause 6. Prolonged storage of the strip can c
46、ause a change in the mechanical properties (increase in hardness and a decrease in elongation), leading to a decrease in drawability. To minimize this effect, the quality HR4 should be specified.
