EN 10025-2 to EN 10025-6. 4.1.2 Grades and qualities The steels for flat and long products specified in EN 10025-2 to EN 10025-6 are subdivided in grades on the basis of the minimum specified yield strength at ambient temperature. The steel grades may be supplied in qualities which are specified in EN 10025-2 to EN 10025-6. 4.2 Designation For the steel grades covered by this document the steel names shall be allocated in accordance with EN 10027-1 and CR 10260; the steel numbers shall be allocated in accordance with EN 10027-2. 5 Information to be supplied by the purchaser 5.1 Mandatory information The following information shall be obtained by the manufacturer at the time of the order: a) quantity to be delivered; b) product form; c) number of the relevant part of this document; d) steel name or the steel number (see EN 10025-2 to EN 10025-6); e) nominal dimensions and tolerances on dimensions and shape (see 7.7.1); f) all required options (see 5.2); g) additional requirements of inspection and testing and inspection documents as specified in EN 10025-2 to EN 10025-6. NOTE The regulated characteristics would be declared in accordance with Annex ZA. 5.2 Options A number of options are specified in Clause 13. In EN 10025-2 to EN 10025-6 options are specified which are specific for those parts. In the event that the purchaser does not indicate his wish to implement any of these options, the supplier shall supply in accordance with the basic specification.

15CuNi5VMoCr6MnCCEV++++++= The content of the elements in the carbon equivalent value formula shall be reported in the inspection document. 7.3 Mechanical properties 7.3.1 General 7.3.1.1 Under the inspection and testing conditions as specified in Clauses 8, 9 and 10 and in the delivery condition as specified in 6.3 the mechanical properties (tensile strength, yield strength, impact strength and elongation) shall comply with the relevant requirements of EN 10025-2 to EN 10025-6.

EN 10025-6 in the normalized or normalized rolled condition as well as after normalizing by heat treatment after delivery. NOTE Products can be susceptible to a deterioration in mechanical strength if they are subjected to incorrect heat treatment processes at higher temperature such as flame straightening, rerolling, etc. Products in the +N delivery condition are less sensitive than other delivery conditions, but it is recommended that guidance is sought from the manufacturer if any higher temperature processing is required. 7.3.1.3 The applicable product thickness is specified in EN 10025-2 to EN 10025-6. 7.3.2 Impact properties 7.3.2.1 Using test pieces of width less than 10 mm the minimum values given in EN 10025-2 to
EN 10025-6 shall be reduced in direct proportion to the cross-sectional area of the test piece. Impact tests shall not be required for nominal thickness < 6 mm. 7.3.2.2 The impact properties of products of certain qualities specified in EN 10025-2 to EN 10025-6 shall be verified by test only at the lowest temperature unless otherwise agreed at the time of the order. See option 3. 7.3.3 Improved deformation properties perpendicular to the surface If agreed at the time of the order products of the grades and qualities specified EN 10025-2 to EN 10025-6 shall comply with one of the improved deformation properties perpendicular to the surface of the product as specified in EN 10164. See option 4. 7.4 Technological properties 7.4.1 Weldability General requirements for welding shall be as given in EN 10025-2 to EN 10025-6. NOTE Due to their favourable chemical composition, in comparison to a normalized steel at the same yield strength level thermomechanically treated steels according to EN 10025-4:2004 exhibit enhanced weldability. 7.4.2 Formability General requirements for formability shall be as given in EN 10025-2 to EN 10025-6.

EN 10025-6:2004). 9.2.2.2 The samples shall be taken as specified in EN 10025-2 to EN 10025-6. The location of samples shall be as Annex A. Additionally for plates, sheet, wide strip and wide flats the samples shall be taken so that the axes of the test pieces are approximately midway between the edge and center line of the products. For wide strip and rod the sample shall be taken at an adequate distance from the end of the product. For narrow strip (< 600 mm wide) the sample shall be taken at an adequate distance from the end of the coil and at one third of the width. 9.2.3 Preparation of test pieces 9.2.3.1 General The requirements of EN ISO 377 shall apply. 9.2.3.2 Tensile test pieces The requirements of EN 10002-1 as appropriate shall apply. Test pieces may be non-proportional but in cases of dispute proportional test pieces having a gauge length Lo = 5,65 √ So shall be used (see 10.2.1). For flat products with a nominal thickness < 3 mm the test pieces shall always have a gauge length
Lo = 80 mm and a width of 20 mm (test piece number 2 EN 10002-1:2001, Annex B). NOTE For bars round test pieces are commonly used but other forms are not prohibited (see EN 10002-1). 9.2.3.3 Impact test pieces The test pieces shall be machined and prepared in accordance with EN 10045-1. In addition the following requirements apply: a) for nominal thicknesses > 12 mm, standard 10 mm × 10 mm test pieces shall be machined in such a way that one side is not further away than 2 mm from a rolled surface, unless otherwise specified in
EN 10025-2 to EN 10025-6; b) for nominal thicknesses ≤ 12 mm, when test pieces with reduced widths are used, the minimum width shall be 5 mm. 9.3 Identification of samples and test pieces Samples and test pieces shall be marked so that the original products and their location and orientation in the product is known.

EN 10025-6:2004 the upper yield strength (ReH) shall be determined. If a yield phenomenon is not present, the 0,2 % proof strength (Rp0,2) shall be determined. In case of dispute, the 0,2 % proof strength shall be used. If a non-proportional test piece is used for products with a thickness ≥ 3 mm the percentage elongation value obtained shall be converted to the value for a gauge length Lo = 5,65 √So using the conversion tables given in EN ISO 2566-1. In the case of plates used for the manufacture of floorplate, the elongation values only apply to the base plate and not to the final floorplate. 10.2.2 Impact tests The impact test shall be carried out in accordance with EN 10045-1. The average value of the three test results shall meet the specified requirement. One individual value may be below the minimum average value specified, provided that it is not less than 70 % of that value. Three additional test pieces shall be taken from the same sample in accordance with 9.2.2.1 and tested in any one of the following cases: − if the average of three impact values is lower than the minimum average value specified; − if the average value meets the specified requirement, but two individual values are lower than the minimum average value specified; − if any one value is lower than 70 % of the minimum average value specified. The average value of the six tests shall be not less than the minimum average value specified. Not more than two of the individual values may be lower than the minimum average value specified and not more than one may be lower than 70 % of this value. 10.3 Ultrasonic testing If specified at the time of the order (see 7.6), ultrasonic testing shall be carried out: − for flat products in thicknesses ≥ 6 mm in accordance with EN 10160;

NOTE This depends on the type of inspection document (see 8.2). 11.2 Marking shall be at a position close to one end of each product or on the end cut face at the manufacturer's discretion, but shall be so positioned as to avoid confusion with regulatory marking. Where regulatory marking also meets the requirements for this clause, this Clause will be deemed to have been satisfied without repetition of the information provided with the regulatory marking. 11.3 It is permissible to supply products in securely tied bundles. In this case the marking shall be on a label attached to the bundle or on the top product of the bundle. 12 Complaints With regard to any claims and action arising, EN 10021 shall apply. 13 Options (see 5.2) For products according to EN 10025-2:2004 to EN 10025-6:2004 the following options apply, if required:
1) The steel making process of the relevant quality shall be reported to the purchaser (see 6.1).
2) Product analysis shall be carried out; the number of samples and the elements to be determined shall be as agreed (see 7.2.2, 8.3.3 and 8.4.2 of EN 10025-2:2004 to EN 10025-6:2004).
3) The impact properties of a quality shall be verified at an agreed temperature (see 7.3.2.2 and 8.4.2 of EN 10025-2:2004 to EN 10025-6:2004).
