25、-1:2006, Clause 1), manufactured from the direct hardening non alloy steels for quenching and tempering and the non alloy flame and induction hardening steels and supplied in one of the heat treatment conditions given for the different types of products in Table 1, lines 2 to 7, and in one of the su

26、rface conditions given in Table 2. The steels are generally intended for the manufacture of quenched and tempered, flame or induction hardened machine parts, but can also be used in the normalized condition. The requirements for mechanical properties given in this document are restricted to the size

27、s given in Table 9 and Table 10. NOTE This document does not apply for bright steel products. For bright steel products EN 10277-1 and EN 10277-5 apply.
