ISO 7452 specifies requirements for tolerances for hot-rolled steel plates made on a reversing mill with the following characteristics:
a) nominal thickness: 3 mm≤t≤400 mm;
b) nominal width: w 2600 mm.
NOTE 1 Tolerances for products of width < 600 mm, cut or slit from plate, may be agreed between the manufacturer and purchaser at the time of ordering.
ISO 7452 applies to, but is not limited to, steel grades defined in all parts of ISO 630,in ISO 9328-1 to ISO 9328-6 and in ISO 683-1, ISO 683-2, ISO 683-10 and ISO 683-11.
This International Standard does not apply to stainless steel.
If not otherwise agreed, the tables in Annex A apply to steel grades defined in Annex A of all parts(except Part 1) of ISO 630 or in ISO 9328-1 to ISO 9328-6.
If not otherwise agreed, the tables in Annex B apply to steel grades defined in Annex B of all parts(except Part 1) of ISO 630 or in ISO 9328-1 to ISO 9328-6.
For steel grades defined in ISO 683-1, ISO 683-2, ISO 683-10 and ISO 683-11, the selection of Annex A or B is done at the time of enquiry and order.
This International Standard does not include continuous mill products, custom-made plate, checker plate or bulb plate for flooring or wide flats.
This International Standard does not include the following steel products, which are covered by other International Standards:
一sheet and strip – refer to ISO/TC 17/SC 12 “Continuous mill flat rolled products”;
一tubular products – refer to ISO/TC 5/SC 1 “Steel tubes”.
NOTE 2 Lists of standards covered by ISO/TC 17/SC 12 and ISO/TC 5/SC 1 are available on the ISO Website.
A number of options are specified. In the event that the purchaser does not indicate his wish to implement any of these options, the supplier shall supply the products in accordance with the basic specifications of this International Standard (see 5.2):
a) whether untrimmed edges (letter NK) are required; when NK is specified, the maximum length and width shall be agreed;
b) whether a limited edge camber and out-of-straightness (letter G) is required; when G is specified,the maximum tolerances for camber and out-of-squareness shall be agreed;
c) whether tolerances on length for plates with a nominal length > 20 000 mm are required (see Table A.3).ISO 7452 pdf download.
