47、 restricted (+HL, +HH) hardenability requirements, the hardenability values given in Table 5 or Table 6 shall apply. 7.1.4 Mechanical properties BS EN 10083-3:2006 EN 10083-3:2006 (E) 8 Where the steel is ordered without hardenability requirements, the requirements for mechanical properties specifie
48、d in Table 8 for the quenched and tempered condition apply. In this case the hardenability values given in Table 5 are for guidance purposes only. The mechanical property values given in Table 8 apply to test pieces in the quenched and tempered condition which have been taken and prepared in accorda
49、nce with EN 10083-1:2006, Figure 1 or Figures 2 and 3 (see also footnote a in Table 1). 7.1.5 Surface hardness For the hardness of surface hardened zones of steels intended for flame and induction hardening the specifications in Table 9 apply. 7.2 Machinability All steels delivered in the soft annealed (+A) condition are machinable.
