27、on 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
28、. 6.3 Mechanical properties The mechanical properties of the products, to be determined by the tensile test, shall be in accordance with the prescriptionsgiien 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) ca
29、n 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 originating from rolled-in scale, shall not be reg
30、arded as defects. Minor surface imperfections that may occur under normal manufacturing conditions, such as scores 6.4.3 6.5 Supplementary or special requirements Any particular surface requirements may be agreed at the time of enquiry and order. 6.5.1 Aptitude to cold forming A test for the verific
31、ation 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 13 d,
32、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 max. diameter of 15 mm. The criteria for the assessment of test re
33、sults shall be agreed at the time of ordering bearing in mind the end use for which the products are intended. 6.5.2 Depth of surface defects The max. admissible depth of surface defects is indicated in Table 8. The depth of a defect is considered as being the distance between the surface of the pro
34、duct and the bottom of the defect, to be measured in a direction perpendicular to the surface along a radius. In case of dispute the determination of the depth of surface defects shall be carried out by metallographic means with a magnification of X 100, on a straight cross-section of the product in
35、 the delivery condition concerned.
