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.

EN 10025-1:2004 (E) 10 6 Manufacturing process 6.1 Steel making process The steel making process is at the discretion of the manufacturer with the exclusion of the open hearth (Siemens-Martin) process. If specified at the time of the order the steel making process of the relevant steel grade shall be reported to the purchaser. See option 1. 6.2 Deoxidation or grain size The method of deoxidation or the required grain size shall be as given in EN 10025-2 to EN 10025-6. 6.3 Delivery conditions The delivery conditions shall be as given in EN 10025-2 to EN 10025-6. 7 Requirements 7.1 General The following requirements apply when sampling, preparation of test pieces and testing specified in Clauses 8, 9 and 10 are carried out. 7.2 Chemical composition 7.2.1 The chemical composition determined by ladle analysis shall comply with the values in the relevant Table of EN 10025-2 to EN 10025-6. 7.2.2 The limits applicable for the product analysis are given in the relevant Table of EN 10025-2 to EN 10025-6. The product analysis shall be carried out when specified at the time of the order. See option 2. 7.2.3 For determining the carbon equivalent value the following IIW (International Institute for Welding) formula shall be used:

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 10025-1:2004 (E) 11 NOTE Stress relieving at more than 580 °C or for over 1 h may lead to a deterioration of the mechanical properties of the steel grades as defined in EN 10025-2 to EN 10025-5. For normalized or normalized rolled steel grades with minimum ReH ≥ 460 MPa1) the maximum stress relief temperature should be 560 °C. If the purchaser intends to stress relief the products at higher temperatures or for longer times than mentioned above the minimum values of the mechanical properties after such a treatment should be agreed at the time of the enquiry and order. For the quenched and tempered steel grades of EN 10025-6:2004 the maximum stress-relief temperature should be at least 30 °C below the tempering temperature. As this temperature is normally not known in advance it is recommended that the purchaser if he intends to perform a post weld heat treatment to contact the steel producer. 7.3.1.2 For products ordered and supplied in the normalized or normalized rolled condition the mechanical properties shall comply with the relevant tables for mechanical properties of EN 10025-2 to

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
