EN 10083-1:2006 (E) 4 1 Scope This part of EN 10083 specifies the general technical d

22、elivery requirements for semi-finished products, hot formed, e.g. blooms, billets, slabs (see NOTES 2 and 3), bars (see NOTE 2), rod, wide flats, hot-rolled strip and sheet/plate, forgings (see NOTE 2) manufactured from the direct hardening non alloy steels for quenching and tempering (see EN 10083-

23、2), the direct hardening alloy steels for quenching and tempering (see EN 10083-3), the non alloy flame and induction hardening steels (see EN 10083-2) and the alloy flame and induction hardening steels (see EN 10083-3), and supplied in one of the heat treatment conditions given for the different ty

24、pes of products in the relevant tables of EN 10083-2 and EN 10083-3 and in one of the surface conditions given in the relevant tables of EN 10083-2 and EN 10083-3. The steels are generally intended for the manufacture of quenched and tempered, flame or induction hardened machine parts, but can also

25、be used in the normalized condition (see EN 10083-2). Where applicable, the requirements for mechanical properties given in EN 10083-2 and EN 10083-3 are restricted to the relevant tables in these documents. NOTE 1 European Standards on similar grades are listed in Annex C. NOTE 2 Hammer forged semi

26、-finished products (blooms, billets, slabs etc.), seamless rolled rings and hammer forged bars are in the following covered under semi-finished products or bars and not under the term “forgings“. NOTE 3 Special agreements should be made when ordering un-worked continuously cast semi-finished product

27、s. NOTE 4 In accordance with EN 10020, the steels covered by EN 10083-2:2006 are quality and special steels, the steels covered by EN 10083-3:2006 are special steels. The differences between quality and special steels are characterized by the following requirements, which are valid for special steel

28、s only: the minimum impact values in the quenched and tempered condition (for non alloy special steels in the case of mean percentages by mass of carbon 0,30 % only); limited oxide inclusion content; lower maximum contents for phosphorus and sulphur. NOTE 5 This European Standard does not apply for

29、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

30、general technical delivery conditions given in EN 10021 are applicable unless otherwise specified.

Independent of the actual shape and dimensions of the cross-section of the product the size of its ruling section is always given by a diameter. This corresponds to the diameter of an “equivalent round bar“. That is, a round ba
