With part 1, replaces the approved standard NF EN 10155 dated August 1993. CorrespondenceThe European standard EN 10025-2:2004 has the status of French standard. AnalysisThis document specifies the technical delivery conditions for flat and long products and semi-finished products intended to be processed into flat and long hot rolled products of quality non-alloy structural steels. Three engineering steels are also specified in this document (see Tables 3 and 5) (chemical composition) and Table 8 (mechanical characteristics). This document does not apply to structural hollow sections (see EN 10210-1 and EN 10219-1). Steels specified in this part are not intended for heat treatment. Stress relieving is allowed (see also note 7.3.1.1 of EN 10025-1:2004). Products delivered in the condition +N can be hot shaped and standardized after delivery (see article 3). This document supports the European standard EN 10025-1 which is harmonized with the European Directive on Construction Products. The conformity of the products of this document with the Directive allows the CE marking on these products.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2005, and conflicting national standards shall be withdrawn at the latest by May 2005. This document supersedes EN 10025:1990 + A1:1993, Hot rolled products of non-alloy structural steels - Technical delivery conditions. The titles of the other Parts of this European Standard are: Part 1: General technical delivery conditions; Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels; Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels; Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion resistance; Part 6: Technical delivery conditions for flat products of high yield strength structural steels in the quenched and tempered condition. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the EU Construction Products Directive (89/106/EEC). For relationship with the EU Construction Products Directive, see informative Annex ZA of EN 10025-1:2004. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. EN 10025-2:2004 (E) 5 1 Scope Part 2 of this document, in addition to Part 1, specifies the technical delivery conditions for flat and long products and semi-finished products which are meant for further processing to flat and long products of hot rolled non-alloy quality steels in the grades and qualities given in Tables 2 to 6 (chemical composition) and Tables 7 to 9 (mechanical properties) in the delivery conditions as given in 6.3. Three engineering steels are also specified in this document (see Tables 3 and 5) (chemical composition) and Table 8 (mechanical properties). This document does not apply to structural hollow sections and tubes (see EN 10210-1 and EN 10219-1). The technical delivery conditions apply to thicknesses 3 mm and 150 mm for long products of steel grade S450J0. The technical delivery conditions apply to thicknesses 250 mm for flat and long products of all other grades and qualities. In addition for flat products of qualities J2 and K2 the technical conditions apply to thicknesses 400 mm. Products made of steel grades S185, E295, E335 and E360 cannot be CE marked. The steels specified in this Part 2 are not intended to be heat treated except products delivered in delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3). NOTE 1 Semi-finished products which are to be converted to rolled finished products conforming to this document should be the subject of special agreement at the time of the enquiry and order. The chemical composition can also be agreed at the time of the order, however the values should be within the limits of Tables 2 and 3. NOTE 2 For certain grades and product forms suitability for particular applications may be specified at the time of the enquiry and order (see 7.4.2, 7.4.3 and Table 10). 2 Normative references The following referenced documents are indispensable for the application of this document.
