ISO 5952:2019 pdf free.Steel sheet, hot-rolled, of structural quality with improved atmospheric corrosion resistance.
At the time that the steel is made available for shipment, the mechanical properties shall be as stated in Table 3 when they are determined on test pieces obtained according to the requirements of Clause 7. Any additional property requirements specified or required are subject to agreement before ordering.
It is desirable that the specified product be identified for fabrication by name of the part or by intended application. Proper identification of the part may include visual examination, prints or description, or a combination of these.
Oxide or scale in hot-rolled steel sheet is subject to variations in thickness, adherence and colour.Removal of the oxide or scale by pickling or blast cleaning may disclose surface imperfections not readily visible prior to this operation.
As a deterrent to rusting, a coating of oil is usually applied to hot-rolled, descaled steel sheet, but sheet may be furnished unoiled, if required. The oil is not intended as a forming lubricant and shall be easily removable with degreasing chemicals. When requested, the manufacturer shall advise the purchaser which type of oil has been used.
The resistance of these steels to atmospheric corrosion is due to the formation of a protective oxide layer. The formation of this protective layer depends not only on chemical composition, such as the distinctive differences between the analyses of the various grades, but also on a number of factors such as surrounding atmosphere, design, etc, over which the steel producer has no control. See Annexes A and B for information on estimating the corrosion resistance and cautions concerning the use of these steels.
The manufacturer has the right to resubmit for acceptance the products that have been rejected during earlier inspection because of unsatisfactory properties, after the rejected products have been subjected to a suitable treatment (e.g. selection, heat treatment), which on request, will be indicated to the purchaser. In this case, tests shall be carried out as if they applied to a new lot.ISO 5952 pdf free download.
