33、ed by the tensile test, shall be in accordance with the Tables 6, 7 and 8 but by considering the prescriptions given in Table 1 and the delivery condition given in Table 2. 6.4 Hardenability 6.4.1 In the case of products ordered with standard requirements regarding hardenability, that is, when the s
34、teel names or numbers as quoted in Tables 3 and 4 are supplemented by the symbol “+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 Tables 9 and 11. 6.4.2 In the case of products ordered with restri
35、cted 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 compliance with the values given in Table 10. NOTE 1 The sy
36、mbol “+HH” denotes that the upper limit of the scatter band coincides with the upper limit for the corresponding steel “+H”.
