38、on The complete designation for ordering a product according to this European Standard shall contain the following information: a) the desired quantity; b) the product form (e.g.: strip or sheet/plate); BS EN 10088-4:2009EN 10088-4:2009 (E) 7 c) the nominal dimensions, the number of the appropriate
39、European Standard (see Annex B) plus any choice of requirements; d) the type of material (steel); e) the number of this European Standard; f) the steel name or steel number; g) the symbol for the desired heat treatment or cold worked condition, if for the relevant steel in the tables for the mechani
40、cal properties more than one treatment condition is covered; h) the desired process route (see symbols in Table 6); i) verification of internal soundness, if required (flat products with thickness 6 mm shall be tested in accordance with EN 10307); j) the type of inspection certificate (3.1 or 3.2) a
41、ccording to EN 10204; k) regulatory marking requirements (see Annex ZA). EXAMPLE 10 plates of a steel grade with the name X5CrNi18-10 and the number 1.4301 as specified in EN 10088-4 with nominal dimensions thickness = 8 mm, width = 2000 mm, length = 5000 mm; tolerances on dimensions, shape and mass

45、orming to this European Standard shall be at the discretion of the manufacturer. 6.2 Delivery condition The products shall be supplied by reference to the process route given in Table 6 and, where different alternatives exist, to the treatment conditions given in Tables 7 to 11, 13 and 14 (see also
46、Annex A). 6.3 Chemical composition 6.3.1 The requirements given in Tables 1 to 4 shall apply with respect to the chemical composition according to the cast analysis. If grades other than those included in this European Standard are required for construction purposes, they shall comply with EN 10088-
47、2 and be in conjunction with the requirements of this European Standard. 6.3.2 The product analysis may deviate from the limiting values for the cast analysis given in Tables 1 to 4 by the values listed in Table 5. 6.4 Chemical corrosion properties Referring to resistance to intergranular corrosion
48、as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic steels the specification in Tables 7, 10 and 11 shall apply. EN ISO 3651-2 shall not be applicable for testing martensitic and precipitation hardening steels. NOTE The corrosion resistance of stainless steels is very depen
49、dant on the type of environment and can therefore not always be clearly ascertained through laboratory tests. It is therefore advisable to draw on the available experience of the use of the steels. 6.5 Mechanical properties 6.5.1 The mechanical properties at room temperature as specified in Tables 7 to 11 shall 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 the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in 7
