ISO 5000:2019 pdf free.Steel sheet, aluminium-silicon alloy-coated by the continuous hot-dip process, of commercial and drawing qualities.
4 Dimensions
4.1 Aluminium-silicon alloy-coated steel sheet is produced in thicknesses from 0,40 mm to 3,0 mm
inclusive and in widths of 600 mm to 1 500 mm in coils and cut lengths. Aluminium-silicon alloy-coated sheet less than 600 mm wide, slit from wide sheet, is considered as sheet.
4.2 The thickness of aluminium-silicon alloy-coated steel sheets may be specified as a combination
of the base metal and metallic coating, or as base metal alone. The purchaser shall indicate on the order which method of specifying thickness is required. In the event that the purchaser does not indicate any preference, the thickness as a combination of the base metal and coating will be provided. Annex A describes the requirements for specifying the thickness as base metal alone.
5 Conditions of manufacture
5.1 Steelmaking
Unless otherwise agreed by the interested parties, the processes used in making the steel and in manufacturing aluminium-silicon alloy-coated sheet are left to the discretion of the manufacturer. On request, the purchaser shall be informed of the steelmaking process being used.
5.2 Chemical composition
The chemical composition (heat analysis) shall conform to the requirements given in Tables 1 and 2.
5.3 Chemical analysis
5.3.1 Heat analysis
An analysis of each heat shall be made by the manufacturer in order to determine conformity with the requirements given in Tables 1 and 2.. On request, a report of the heat analysis shall be made available to the purchaser or the purchaser’s representative. Each of the elements listed in Tables 1 and 2 shall be included in the report of the heat analysis. When the amount of copper, nickel, chromium or molybdenum present is less than (J(J2 %, the analysis may be reported as ‘<0,02%”.
5.3.2 Product analysis
A product analysis may be made by the purchaser in order to verify the specified analysis of the product and shall take into consideration any normal heterogeneity. The product analysis shall be in accordance with Tables 2 and 3.
The sum of copper, nickel, chromium and molybdenum shall not exceed 0,50 % on heat analysis. When one or more of these elements are specified, the Sum does not apply, In which case only the individual limits on the remaining elements apply.
b The sum of chromium and molybdenum shall not exceed 0,16 % on heat analysis. When one or more of these elements arc specified, the sum docs not apply, in which case, only the individual limits on the remaining elements apply.
C For interstitial free steels only, the value of 0,15 % titanium, and 0,10 % maximum for niobium and vanadium are acceptable to ensure that the carbon and nitrogen arc fully stabilized.
d Heat analysis greater than 0,008 % may be supplied after agreement between producer and purchaser.Aluminium-silicon alloy-coated steel sheet of designations 02 and 03 are supplied under either of the following two ordering conditions.
a) Ordering condition A: steel sheet mechanical properties shall, at the time the steel is made available for shipment, satisfy the applicable requirements of Table 4, when they arc determined on test pieces obtained in accordance with the requirements in Clause 7. The values specified in Table 4 are applicable for the periods indicated in Table 5 from the time that the steel is available for shipment. b) Ordering condition B: steel sheet, ordered to make an identified part, shall be supplied with a commitment for satisfactory manufacturing performance within an established breakage allowance, which shall be previously agreed upon by the interested parties. In the agreement, the part name, the details of fabrication, and special requirements (such as freedom from stretcher strain or fluting) shall be specified. In the case of ordering condition 13, mechanical properties of the steel sheet may also he agreed upon by the interested parties and such properties may not necessarily satisfy the requirements of Table 4.ISO 5000 pdf download.
