22、 has been prepared by Technical Committee ECISS/TC 105 “Steels for heat treatment, alloy steels, free-cutting steels and stainless steels”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or
23、by endorsement, at the latest by December 2018 and conflicting national standards shall be withdrawn at the latest by December 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying
24、 any or all such patent rights. This document supersedes EN 10277-1:2008 to EN 10277-5:2008. The following changes have been made in comparison to the previous edition EN 10277-1:2008 to EN 10277-5:2008: a) the five parts of EN 10277-1 to EN 10277-5 were merged into one part; b) the dimensional requ
25、irements for bright steel products were added to this standard; c) for the steels for general engineering use, the steel grades E295GC, E355GC, C10, C15, C16 and C55 were deleted and the grades C25, C30 and C50 were added; d) for the free cutting steels, the grades 9S20, 17SMn20, 35SMn20 and 35SMnPb
26、20 were added; e) for the case hardening steels, the grades 16MnCrB 5, 15NiCrS4, 15NiCr13 and 17NiCrMoS6-4 were deleted, the grades C10E, C15E, C16E, 16MnCr5, 20Cr4, 20CrS4, 20MnCr5, 24CrMo4, 24CrMoS4, 16NiCr4, 16NiCrS4, 20NiCrMo2-2, 17NiCrMo6-4, 17NiCrMoS6-4 and 18CrNiMo7-6 were added; f) for the s
27、teels for quenching and hardening, the grade 39NiCrMo3 was deleted, the grades C25E. C25R. C30E, C30R, 28Mn6, 36Mn6, 42Mn6, 34Cr4, 37Cr4, 37CrS4, 41Cr4, 25CrMo4, 34CrMo4, 34CrMoS4, 42CrMo4, 50CrMo4 36CrNiMo4 and 30CrNiMo8 were added; g) the standard was editorially revised. This standard is the resu
28、lt of the work on ISO 683-18. Since the bright stainless steel products are to be found in EN 10088-3 for European standardization, they are excluded here. In addition, this standard was adapted to include the European references and some further amendments were made. According to the CEN-CENELEC In
29、ternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,
30、 Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 10277:2018EN 10277:2018 (E) 4 1 Scope This document specifies the technical delivery requirements for br
31、ight steel bars in the drawn, peeled/turned or ground condition and they are intended for mechanical purposes, for example for machine parts. The bright bars are subdivided into the following steel types: a) non-alloy general engineering steels; b) non-alloy free-cutting steels; c) non-alloy and all
32、oy case-hardening steels; d) non-alloy and alloy steels for quenching and tempering. This document lists the mechanical characteristics for products up to 100 mm in thickness. For larger dimensions, the manufacturer and purchaser agree on mechanical properties at the time of enquiry and order. It do
33、es not cover cold rolled products and cut lengths produced from strip or sheet by cutting. Bright steel products of stainless steels are to be found in EN 10088-3. In addition to this document, the general technical delivery requirements of EN 10021 are applicable. 2 Normative references The followi
34、ng documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies.

44、s of various cross-sectional shapes obtained, after descaling, by cold drawing of hot-rolled bars or rod, on a drawing bench (cold formation without removing material) Note 1 to entry: This operation gives the product special features with respect to shape, dimensional accuracy and surface finish.

This corresponds to the diameter of an “equivalent round bar”. That is a round bar which will show the same cooling rate as the actual ruling section of the product concerned
