> 0,30 % only); limited oxide inclusion content; lower maximum contents for phosphorus and sulphur. NOTE 5 This European Standard does not apply for bright steel products. For bright steel products
EN 10277-1 and EN 10277-5 apply. In special cases, variations in these technical delivery requirements or additions to them may be agreed at the time of enquiry and order (see Annex B). In addition to the specifications of this European Standard, the general technical delivery conditions given in EN 10021 are applicable unless otherwise specified.
EN 10083-3. 4.2 Designation 4.2.1 Steel names For the steel grades covered by this European Standard, the steel names as given in the relevant tables of EN 10083-2 and EN 10083-3 shall be allocated in accordance with EN 10027-1. 4.2.2 Steel numbers For the steel grades covered by this European Standard, the steel numbers as given in the relevant tables of EN 10083-2 and EN 10083-3 shall be allocated in accordance with EN 10027-2.

The product analysis shall be carried out when specified at the time of the order (see B.6). 7.1.2 Hardenability Where the steel is ordered by using the symbols for normal (+H) or restricted (+HL, +HH) hardenability requirements, the hardenability values given in the relevant tables of EN 10083-2 and
EN 10083-3 shall apply. 7.1.3 Mechanical properties Where the steel is ordered without hardenability requirements, the requirements for mechanical properties specified in EN 10083-2 and EN 10083-3 apply as appropriate for the particular heat treatment condition. The mechanical property values given in EN 10083-2 and EN 10083-3 apply to test pieces in the quenched and tempered or normalized condition which have been taken and prepared in accordance with Figure 1 or Figures 2 and 3. 7.2 Machinability All steels delivered in the soft annealed (+A) condition are machinable. Where improved machinability is required, the grades with a specified sulphur range should be ordered and/or with a specific treatment to improve machinability (e.g. Ca treatment). 7.3 Shearability of semi-finished products and bars The relevant specifications in EN 10083-2 and EN 10083-3 shall apply. 7.4 Structure The requirements specified in the relevant clauses of EN 10083-2 and EN 10083-3 shall apply. Regarding fine grain requirements and/or verification of fine grain size see B.3. Regarding the verification of non-metallic inclusion content of special steels see B.4. NOTE Segregation is the result of a natural phenomenon. Segregations can be found in ingots as well as in slabs, blooms and billets from the continuous casting process. The positive segregation is a concentration of various elements at different locations in the ingot, slab, bloom and billet. In case of flat products customers should note, that these segregations can occur parallel to the surface of the product. Especially for medium and high carbon contents segregations lead to a higher hardness and should be taken into consideration during further heat treatments.
