The product analysi
47、s shall be carried out when specified at the time of the order (see A.5). 7.1.3 Hardenability Where the steel is ordered by using the symbols for normal (+H) or restricted (+HL, +HH) hardenability requirements, the hardenability values given in Table 5 or Table 6 shall apply. 7.1.4 Mechanical proper
48、ties BS EN 10083-3:2006EN 10083-3:2006 (E) 8 Where the steel is ordered without hardenability requirements, the requirements for mechanical properties specified in Table 8 for the quenched and tempered condition apply. In this case the hardenability values given in Table 5 are for guidance purposes
49、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 accordance 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.
