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 committee 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 electrotechnical 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 member 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 identifying any or all such patent rights. ISO 16143-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and alloy steels. ISO 16143 consists of the following parts, under the general title Stainless steels for general purposes: Part 1: Flat products Part 2: Semi-finished products, bars, rods and sections Part 3: Wire Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Hong Kong Polytechnic Univ/9976803100 Not for Resale, 04/17/2007 10:10:01 MDTNo reproduction or networking permitted without license from IHS -,-,- INTERNATIONAL STANDARD ISO 16143-1:2004(E) © ISO 2004 All rights reserved 1 Stainless steels for general purposes Part 1: Flat products 1 Scope This part of ISO 16143 specifies the technical delivery conditions for hot- or cold-rolled sheet/plate and strip for general purposes made of the most important corrosion-resistant stainless steel grades. NOTE In the text, under the term “general purposes”, purposes other than the special purposes mentioned in the bibliographic references 1 4 are understood. In addition to this part of ISO 16143, the general technical delivery requirements of ISO 404 are applicable. This part of ISO 16143 does not apply to components manufactured by further processing of the product forms listed in paragraph 1 where quality characteristics are altered as a result of such processing. 2 Normative references The following referenced documents are indispensable for the application of this document.

Such requirements to be considered include, but are not limited to, the following: a) the desired quantity; b) the product form (strip or sheet/plate); c) the number of the appropriate dimensional standard (see ISO 9444, ISO 9445 and ISO 18286), the nominal dimensions, plus any choice of requirements; d) the type of material (steel); e) the number of this International Standard, i.e. ISO 16143-1; f) the steel name; g) if, for the relevant steel in Tables 4 to 8, more than one treatment condition is covered, the symbol for the desired heat treatment; h) the desired process route (see Table 3); i) if an inspection document is required, its designation in accordance with ISO 10474. EXAMPLE 5 t of cold-rolled narrow strip in accordance with ISO 9445 with a specified thickness of 0,25 mm, precision thickness tolerance (P), with a specified width of 250 mm, precision tolerance on width (P) and with restricted tolerances on edge camber (R) made of steel grade X5CrNi18-9 as specified in ISO 16143-1, in process route 2D and inspection certificate 3.1.B as specified in ISO 10474 is designated as follows: 5 t cold-rolled narrow strip ISO 9445 0,25P × × × × 250P R Steel ISO 16143-1-X5CrNi18-9 + + + + 2D 3.1 B Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Hong Kong Polytechnic Univ/9976803100 Not for Resale, 04/17/2007 10:10:01 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 16143-1:2004(E) © ISO 2004 All rights reserved 3 6 Classification of grades Corrosion-resistant stainless steels covered in this part of ISO 16143 are classified according to their structure into: austenitic steels; austenitic-ferritic steels; ferritic steels; martensitic steels; precipitation-hardening steels. 7 Requirements 7.1 Manufacturing process Unless a special steelmaking process is agreed upon at the time of ordering, the steelmaking process shall be at the discretion of the manufacturer. When he so requests, the purchaser shall be informed what steelmaking process is being used. 7.2 Delivery condition The products shall be supplied in the delivery condition agreed upon in the order, by reference to the process route given in Table 3 and, where different alternatives exist, to the treatment conditions given in Tables 4 to 8 (also see Annex A). 7.3 Chemical composition 7.3.1 The chemical composition requirements given in Table 1 apply with respect to the chemical composition of the cast analysis. 7.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Table 1 by the values listed in Table 2. 7.4 Susceptibility to intergranular corrosion Referring to resistance to intergranular corrosion as defined in ISO 3651-2, for ferritic, austenitic and austenitic-ferritic steels the specification in Tables 4, 5 and 6 apply. NOTE The susceptibility of stainless steels to intergranular corrosion is dependent on the type of environment and therefore cannot always be clearly ascertained through standard laboratory tests. The selection of the test or tests to be agreed upon should be based on experience with the use of the selected grade of steel in the intended environment. 7.5 Mechanical properties The mechanical properties at room temperature as specified in Tables 4 to 8 apply for the relevant specified heat-treatment condition. This does not apply to the process route 1U (hot rolled, not heat-treated, not descaled). If, by agreement at the time of ordering, the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in Tables 4 to 8 shall be obtainable from reference test pieces which have received the appropriate heat treatment (simulated heat treatment). NOTE Austenitic steels are insensitive to brittle fracture in the solution-annealed condition. Because they do not have a pronounced transition temperature, which is characteristic of other steels, they are also useful for application at cryogenic temperatures.

When products are delivered in coil form, the degree and extent of imperfections may be expected to be greater, due to the impracticability of removing short lengths of coil. Where necessary, precise requirements on surface quality may be agreed upon at the time of enquiry and order. 7.7 Internal soundness For the internal soundness, where appropriate, requirements together with the conditions for their verification may be agreed upon at the time of enquiry and order. 7.8 Dimensions, tolerances on dimensions and shape The dimensions and the tolerances on dimensions and shape are to be agreed upon at the time of enquiry and order, as far as possible with reference to the dimensional standards ISO 9444, ISO 9445 and ISO 18286. 7.9 Calculation of mass and tolerance of mass 7.9.1 The density values of the relevant grades for calculating the nominal mass of the products shall be taken from Annex B of ISO/TS 15510:2003. 7.9.2 If the tolerances on mass are not specified in the dimensional standards mentioned in 7.8, th
