3? Terms? and? definitions For the purposes of this document, the terms and definitions given in EN 10263-1 and the following apply. 3.1 stainless steels steels with at least 10,5 % Cr and max. 1,2 % C (mass fraction) 4? Classification? and? designation 4.1? Classification All steels covered by this part of EN 10263 are stainless steels according to EN 10020. From a practical viewpoint these steels are also classified on the basis of their structure; see also EN 10088‑1:2014, Annex C. 4.2 Designation See EN 10263‑1. 5 Production Process See EN 10263‑1.
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 Table 1 and Table 2. 6.2 Chemical composition 6.2.1 Cast analysis The chemical 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 mechanical properties of the products, to be determined by the tensile test, shall be in accordance with the prescriptions given in Table 5, Table 6, Table 7 and Table 8.
6.4 Surface quality 6.4.1 Rod is normally supplied in the pickled condition. Mechanical descaling (sandblasting) can also be used, in which case a subsequent treatment in a pickling solution shall be carried out unless otherwise agreed. Particular processes such as peeling or shaving may also be applied, subject to specific agreement at the time of enquiry and order.6.4.2 Minor surface imperfections which may occur under normal manufacturing conditions, such as scores originating from rolled‑in scale, shall not be regarded as defects. 6.4.3 Any particular surface requirements may be agreed at the time of enquiry and order. 6.5 Supplementary or special requirements 6.5.1 Aptitude to cold forming A test for the verification of the aptitude of products to cold forming may be carried out if agreed at the time of enquiry and order. If for the verification of the aptitude to cold forming the upsetting test is applied, it shall be carried out as follows: — a test piece with an initial length (height) equal to 1,5 x d, where d is the product diameter, is submitted to axial heading by means of a press until its length is reduced to 1/3 of the initial value. The above test shall be carried out at ambient temperature and limited to the products with a maximum diameter of 15 mm. The criteria for the assessment of test results shall be agreed at the time of ordering bearing in mind the end use for which the products are intended.BS EN 10263‑5 pdf download.
