19、iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intere
20、sted 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 Electrotechnical
21、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 adopted by the tec
22、hnical 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 patent rights. ISO
23、 shall not be held responsible for identifying any or all such patent rights. ISO 9444-2 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and alloy steels. This first edition of ISO 9444-2 cancels and replaces the second edition of ISO 9444:2002, the contents o
24、f which has been technically revised and separated into two parts. ISO 9444 consists of the following parts, under the general title Continuously hot-rolled stainless steel Tolerances on dimensions and form: Part 1: Narrow strip and cut lengths Part 2: Wide strip and sheet/plate BS EN ISO 9444-2:201

26、eel wide strip in actual widths from 600 mm to 2 500 mm and for sheet/plate cut from such strip. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest
27、edition of the referenced document (including any amendments) applies. ISO 6929:1987, Steel products Definitions and classification 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 6929 and the following apply. 3.1 hot-rolled sheet/plate flat rolled p
28、roduct, the edges being allowed to deform freely, supplied flat and generally square or rectangular, but also in any other shape, for example circular or according to the design sketch; the edges are as-rolled or sheared or flame-cut or chamfered NOTE 1 The product may also be delivered precurved. N
29、OTE 2 Hot-rolled sheet/plate may be produced: a) directly rolled on a reversing mill, or by cutting from a parent plate rolled on a reversing mill; b) by cutting from hot-rolled strip rolled on a continuous mill. NOTE 3 Reversing-mill plate is known generally as “quarto-plate”. Continuous-mill sheet
30、/plate is known generally as “hot-rolled sheet/plate”. NOTE 4 Where further subdivision is required to be made on the basis of thickness for statistical purposes, the following is recommended: a) sheet: thickness less than 3 mm (except electrical sheet); b) plate: thickness equal to or greater than
31、3 mm. NOTE 5 Adapted from ISO 6929:1987, definition 6.2.6.2.2.2. BS EN ISO 9444-2:2010ISO 9444-2:2009(E) 2 ISO 2009 All rights reserved3.2 hot-rolled strip hot-rolled flat product which immediately after the final rolling pass or after pickling or annealing is wound into laps so as to form a coil NO
32、TE 1 Hot-rolled strip as-rolled has slightly convex edges, but it may also be supplied with sheared edges or be obtained by slitting wider hot-rolled strip. ISO 6929:1987, definition 6.2.6.2.2.3.1 NOTE 2 According to its actual width, including hot-rolled slit strips irrespective of the rolling widt
33、h, hot-rolled strip is classified as hot-rolled wide strip: strip of a width equal to or greater than 600 mm, or hot-rolled narrow strip: strip of a width less than 600 mm. After decoiling and cutting to length, hot-rolled narrow strip may be supplied as cut lengths. 4 Information to be supplied by
34、the purchaser 4.1 It shall be the responsibility of the purchaser to specify all requirements that are necessary for products under this specification.
