40、 as: shrink holes, segregation, cracks, folds, incrustations, notches, scabs, rolling burrs, damage, which may be prejudicial to its correct use. 3.3 Soundness The rod shall not have any surface discontinuities of depth greateer than the values shown in Table 3. These limit values apply for the test
41、 chosen according to EN 10016-1 (clauses 9.5.1 and 9.6.2).

The maximum point of decarburization shall not exceed twice the limit of Table 4. Th
43、ese limit values are applicable for the test described in EN 10016-1 (clause 9.5.2).

Not more than 10 % of the samples t
45、ested shall be of class 4; class 5 is not allowed (see EN 10016/1, Annex A). It is recommended to do the evaluation as part of a quality assurance system. 3.7 Mechanical properties At the request of the purchaser at the time of ordering, the manufacturer shall notify indicative values of tensile str
