5、SO/TC 17 “Steel” in collaboration with Technical Committee ECISS/TC 105 “Steels for heat treatment, alloy steels, free-cutting steels and stainless steels” (Secretariat: DIN, Germany).

Amendments This standard differs from DIN EN 10051:1997-11 as follows: a) DIN EN ISO 9444-2 was published because separate standards for stainless steel products are needed. Previously, stainless steel plates as in

7、this standard were included in the scope of DIN EN 10051:1997-11.

22、 stainless steel 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

23、, the latest 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

24、flat rolled product, 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

25、 precurved. NOTE 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”. Continuo

26、us-mill sheet/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

27、greater than 3 mm. NOTE 5 Adapted from ISO 6929:1987, definition 6.2.6.2.2.2. DIN EN ISO 9444-2:2010-11 EN ISO 9444-2:2010 (E) 4 3.2 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 NOTE 1 H

28、ot-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 width, hot

29、-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 the pu
