and ordering 4.1 Designation of steel grades The steel names and steel numbers (see Tables to 5) are allocated in accordance with EN 10027-1 and EN 10027-2 respectively 4.2 Order designation The complete designation for ordering a product according to this European Standard shall contain the following information: a) the desired quantity; BS EN 10088-5:2009 EN 10088-5:2009 (E) b) the product form (e g round bars, square bars or rod); c) the nominal dimensions and, where an appropriate dimensional standard is available, (see Table and Annex B) the number of the standard plus any choice of requirements; d) if there is no dimensional standard, the nominal dimensions and tolerances required; e) the type of material (steel); f) the number of this European Standard; g) the steel name or steel number; h) the symbol for the desired heat treatment or cold worked condition, if for the relevant steel in the tables for the mechanical properties more than one treatment condition is covered; i) the desired condition (see symbols in Table 7); j) verification of internal soundness, if required; k) the type of inspection certificate (3.1 or 3.2) according to EN 10204; l) regulatory marking requirements (see Annex ZA) EXAMPLE 10 t round bars of a steel grade with the name X5CrNi18-10 and the number 1.4301 as specified in EN 10088-5 of 50 mm diameter, dimensional tolerances as specified in EN 10060, in condition 1D (see Table 7), inspection certificate 3.1 as specified in EN 10204 and declaration of conformity: 10 t round bars EN 10060-50 Steel EN 10088-5-X5CrNi18-10+1D Inspection certificate 3.1, CE or 10 t round bars EN 10060-50 Steel EN 10088-5-1.4301+1D Inspection certificate 3.1, CE Classification of grades Steels covered in this European Standard are classified according to their structure into a) ferritic steels; b) martensitic steels; c) precipitation hardening steels; d) austenitic steels; e) austenitic-ferritic steels See also Annex B to EN 10088-1:2005 BS EN 10088-5:2009 EN 10088-5:2009 (E) Requirements 6.1 Steelmaking process Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing process for steels conforming 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 and, where different alternatives exist, to the treatment conditions given in Tables to 18 and 20 (see also Annex A) 6.3 Chemical composition 6.3.1 The requirements given in Tables to shall apply in respect of 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 10088-3 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 to by the values listed in Table 6.4 Chemical corrosion properties Referring to resistance to intergranular corrosion as defined in EN ISO 3651-2, for ferritic, austenitic and austenitic-ferritic stainless steels the specifications in Tables 8, 11 and 12 apply EN ISO 3651-2 shall not be not applicable for testing martensitic and precipitation hardening steels NOTE The corrosion resistance of stainless steels is very dependent 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 to 12 shall apply for hot worked products of every condition, condition 1U excluded, for cold processed products in condition 2D (excluding wire), and for each specified heat treatment condition For cold processed products of every specified condition, condition 2D and wire excluded, and each specified heat treatment condition, the mechanical properties at room temperature as specified in Tables 13 to 17 shall apply For these products, the condition is the prime property with the mechanical properties secondary If the products are to be supplied in a non-heat-treated condition, the mechanical properties specified in Tables to 17 shall be obtained from reference test pieces which have received the appropriate heat treatment (simulated heat treatment) For wire, the properties as specified in Table 18 shall apply For bars which are intentionally cold work hardened in order to increase their tensile strength to a specified level, the mechanical properties at room temperature as specified in Table 20 shall apply For these products, the mechanical properties are prime, with the condition a secondary property
