10、SO (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 interested in a subject for which a technical c

11、ommittee 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 Commission (IEC) on all matters of electr

12、otechnical 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 technical committees are circulated to the m

13、ember 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 shall not be held responsible for identi

14、fying any or all such patent rights. ISO 5000 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 12, Continuous mill flat rolled products. This fourth edition cancels and replaces the third edition (ISO 5000:2005), which has been technically revised. INTERNATIONAL STANDARD ISO 500

15、0:2011(E) ISO 2011 All rights reserved 1Continuous hot-dip aluminium-silicon-coated cold-reduced carbon steel sheet of commercial and drawing qualities 1 Scope This International Standard specifies the characteristics of cold-reduced carbon steel sheet of commercial and drawing qualities coated by a

16、 continuous hot-dip aluminium-silicon alloy coating process. Aluminium-silicon-coated steel sheets are used for heat-resisting applications and also where both corrosion and heat resistance are required. The steel sheet is produced in a number of qualities, coating mass, grades, surface treatments a

17、nd conditions designed to be compatible with differing application requirements. Aluminium-silicon-coated steel sheet can be ordered in one of two ordering conditions: a) Condition A): steel ordered to satisfy mechanical property requirements; b) Condition B): steel ordered to make an identified par

18、t. 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 edition of the referenced document (including any amendments) applies. ISO 6353 (all parts), R

20、his document, the following terms and definitions apply. 3.1 Quality applications 3.1.1 commercial intended for general fabricating purposes where sheet is used in the flat condition, or for bending or moderate forming 3.1.2 drawing intended for parts where drawing or severe forming may be involved

21、ISO 5000:2011(E) 2 ISO 2011 All rights reserved3.1.3 deep drawing intended for parts where severe forming or severe drawing may be involved 3.1.4 deep-drawing aluminium killed (non-ageing) intended for fabricating parts where particularly severe drawing or forming may be involved or essential freedo

22、m from ageing is required 3.1.5 extra-deep drawing (stabilized) intended for applications requiring interstitial free steel (IF) which is non-aging and has maximum formability 3.2 aluminium killed steel which has been deoxidized with aluminium that is sufficient to prevent the evolution of gas durin

23、g solidification 3.3 stabilized interstitial free steel extra-low-carbon steel in which all interstitial elements are combined with titanium and/or equivalent elements NOTE Stabilized steel is sometimes referred to as interstitial free steel. 3.4 skin pass light cold-rolling of the product NOTE The

24、purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition known as stretcher strain (Lders lines) or fluting during the fabrication of finished parts. The ski

25、n pass also controls and improves flatness. Some increase in hardness and some loss of ductility will result from skin passing. 3.5 strain ageing change in steel properties with the passage of time NOTE Strain ageing may result in surface imperfections such as stretcher strain marks (Lders lines), f

26、luting when the steel is formed, and a deterioration in ductility. To avoid these adverse outcomes, the period between final processing at the producing mill and fabrication needs to be kept to a minimum. Rotation of stock, by using the oldest material first, is important. Effective roller-levelling

27、 immediately prior to fabrication can achieve reasonable freedom from stretcher strain marks. 3.6 lot 50 t or less of sheet of the same quality rolled to the same thickness and coating condition 4 Thickness 4.1 Aluminium-silicon-coated steel sheet is produced in thicknesses from 0,40 mm to 3,0 mm in

28、clusive and in widths of 600 mm to 1 500 mm in coils and cut lengths. Aluminium-silicon-coated sheet less than 600 mm wide may be slit from wide sheet and will be considered as sheet. 4.2 The thickness of aluminium-silicon-coated steel sheet may be specified as a combination of the base metal and me

29、tallic coating, or as base metal alone. The purchaser shall indicate on the order which method of specifying 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 requirement

30、s for specifying the thickness as base metal alone. ISO 5000:2011(E) ISO 2011 All rights reserved 35 Conditions of manufacture 5.1 Chemical composition The chemical composition (heat analysis) shall not exceed the values given in Tables 1 and 2. On request, a report of the heat analysis shall be mad

31、e to the purchaser. A verification analysis may be made by the purchaser to verify the specified analysis of the product and shall take into consideration any normal heterogeneity. Non-killed steels (such as rimmed or capped steels) are not technologically suited for product analysis. For killed ste

32、els, the sampling method and deviation limits shall be agreed upon between the interested parties at the time of ordering. The product analysis tolerances are shown in Table 3. The processes used in making the steel and in manufacturing aluminium-silicon-coated sheet are left to the discretion of th

33、e manufacturer. When requested, the purchaser shall be informed of the steel-making process used. Table 1 Chemical composition, % (mass fraction) Quality Designation Name C % max. Mn % max.

41、anical properties (ordering condition A) shall, at the time of shipment, satisfy the applicable requirements of Table 4. 5.2.2 Aluminium-silicon-coated steel sheet ordered to make an identified part (ordering condition B) shall be supplied with a commitment to satisfactory performance within a prope

42、rly established breakage allowance, which shall be previously agreed upon by the interested parties. This ordering condition applies to steel sheet qualities 02, 03, 04 and 05. In these cases, the part name, details of fabrication and special requirements shall be specified. NOTE Prolonged storing o

43、f the sheet can result in a change in mechanical properties (increase in hardness and decrease in elongation) leading to a decrease in formability. To minimize this effect, qualities 04 and 05 should be specified. 5.2.3 Aluminium-silicon-coated steel sheet is available in several fabrication qualiti

44、es. Commercial: intended for general fabrication purposes where sheet is used in the flat state or for bending or moderate forming. Drawing: intended for fabricating parts where drawing or severe forming may be involved. Deep drawing: intended for fabricating parts where severe drawing or severe for

45、ming may be involved. Deep-drawing aluminium killed (non-ageing): intended for fabricating parts where particularly severe drawing or forming may be involved or essential freedom from ageing is required. Extra-deep drawing (stabilized interstitial free): intended for applications requiring interstit

46、ial free steel (IF), which is non-ageing and has maximum formability. 5.3 Coating 5.3.1 Silicon content The aluminium-silicon alloy used for coating normally has between 5 % and 11 % silicon added to promote better adherence and heat resistance. 5.3.2 Coating mass The coating mass shall conform to t

47、he limits for the quality designations listed in Table 5. The coating mass is the total amount of coating on both sides of the sheet, expressed in grams per square metre.
