28、nd wire with a diameter up to and including 100 mm, of non-alloy and alloy steel, intended for cold heading and cold extrusion and case hardening. 1.2 EN 10263-1:2017 is indispensable for this part of EN 10263. 2 Normative references The following documents, in whole or in part, are normatively refe
29、renced in this document and are indispensable for its application. For dated references, only the edition cited applies.

30、7, Steel rod, bars and wire for cold heading and cold extrusion Part 1: General technical delivery conditions 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 10263-1:2017 and the following apply. 3.1 case-hardening steels structural steels with a rela
31、tively low carbon content, which are carburized or carbonitrided on their surface and subsequently hardened Note 1 to entry: These steels, after hardening, have a high degree of hardness in the surface zone and good resistance to wear, while the core material is characterized principally by extreme
32、toughness. Note 2 to entry: Further possibilities for heat treatment of case-hardening steels are, for example, nitrocarburizing and nitriding. 4 Classification and Designation 4.1 Classification All steels covered by this part of EN 10263 are special steels according to EN 10020. Steel grades from
33、C10E2C to C20E2C as quoted in Table 3 are non-alloy steels and all others are alloy steels according to EN 10020. 4.2 Designation See EN 10263-1:2017. BS EN 10263-3:2017EN 10263-3:2017 (E) 5 5 Production process 5.1 Steelmaking process See EN 10263-1:2017. 5.2 Deoxidation All steels quoted in Table
34、3 shall be deoxidised. 6 Requirements 6.1 Delivery conditions The delivery conditions in which the products covered by this part of EN 10263 are normally supplied, the product forms and the applicable requirements are given in Tables 1 and 2. 6.2 Chemical composition 6.2.1 Cast analysis The chemical
35、 composition shall be in accordance with the values specified in Table 3 for the cast analysis. 6.2.2 Product analysis In cases where a product analysis is requested, the admissible deviations from the values specified for the cast analysis are indicated in Table 4. 6.3 Mechanical properties The mec
36、hanical properties of the products, to be determined by the tensile test or hardness test, shall be in accordance with Tables 5, 6 and 7 but by consideration of the prescriptions given in Table 1 and of the delivery conditions given in Table 2. 6.4 Hardenability 6.4.1 In the case of products ordered
37、 with standard requirements regarding hardenability, that is, when the steel names or numbers as quoted in Table 3 are supplemented by the symbols “+H”, the hardness values obtained in the end quench test (Jominy test) (see Table 1 of EN 10263-1:2017) shall be in compliance with the values given in
38、Table 8. 6.4.2 In the case of products ordered with restricted requirements regarding the scatter bands of the hardness values obtained by the Jominy test, that is when the steel name or number as quoted in Table 3 is supplemented by the symbol “+HH” or “+HL”, the above hardness values shall be in c
39、ompliance with the values given in Table 9. NOTE 1 The symbol “+HH” denotes that the upper limit of the scatter band coincides with the upper limit for the corresponding steel “+H”. NOTE 2 The symbol “+HL” denotes that the lower limit of the scatter band coincides with the lower limit for the corres
40、ponding steel “+H”. NOTE 3 See EN 10263-1:2017, 7.7.4 and 10.2 6.4.3 The austenizing temperatures for the Jominy test are given in Tables 8 and 9.
