— 25 mm for ferritic and austenitic-ferritic steels;
— 50 mm for austenitic steels;
— 1 00 mm for martensitic steels.
1.2 This part of EN 1 0263 is complemented by EN 1 0263-1 .

3 Terms and definitions
For the purposes of this standard the definitions in EN 1 0263-1 :2001 and the following apply.
3.1
stainless steels
steels with at least 1 0,5 % of Cr and max. 1 ,2 % C are considered as stainless steels if their resistance to corrosion is of primary importance
4 Classification and designation
4.1 Classification
All steels covered by this part of EN 1 0263 standard are special alloy steel according to EN 1 0020.
From a practical viewpoint these steels are also classified on the basis of their structure, see also annex B of EN 1 0088-1 :1 995.
4.2 Designation
See EN 1 0263-1 :2001 .
5 Production Process
See EN 1 0263-1 :2001 .
6 Requirements
6.1 Delivery conditions
The delivery conditions in which the products covered by this part of EN 1 0263 are normally supplied, the product forms and the applicable requirements are given in Table 1 .
6.2 Chemical composition
6.2.1 Heat analysis
The chemical composition shall be in accordance with the values specified in Table 2 for the heat analysis.
6.2.2 Product analysis
In cases where a product analysis is requested, the admissible deviations from the values specified for the heat analysis are indicated in Table 3.
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 Tables 4, 5, 6 and 7.
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 can also be applied, subject to specific agreement at the time of enquiry and order.
6.4.2 Minor surface imperfections that 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.
