23、s of wrought steels and alloys listed in Table 1 and Table 2, which are usually employed for components and equipment, for which the main requirement is their creep resistance under mechanical long-time stressing at temperatures above 500 C. NOTE Heat resisting grades given in EN 10095 9 may also be
24、 used for similar applications if so agreed. 1.2 This European Standard specifies the technical delivery conditions for semi-finished products, for hot or cold rolled sheet/plate and strip, hot or cold formed (cold drawn) bars, rods, wire and sections. 1.3 The general technical delivery conditions s
25、pecified in EN 10021 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard. 1.4 This European Standard does not apply to components manufactured by further processing the product forms listed in 1.2 with quality characteristics altere
26、d as a result of such further processing. 1.5 This European Standard shall not be used for aerospace and pressure purposes. 1.6 For steels and alloys with similar chemical composition, but intended for different applications, see the Bibliography. 2 Normative references The following referenced docu
