1.1This European Standard covers the grades 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.NOTEHeat resisting grades given in EN 10095 [9] may also be used for similar applications if so agreed.1.2This 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. 1.3The general technical delivery conditions specified in EN 10021:2006 apply in addition to the specifications of this European Standard, unless otherwise specified in this European Standard.1.4This European Standard does not apply to components manufactured by further processing the product forms listed in 1.2 with quality characteristics altered as a result of such further processing.1.5This European Standard shall not be used for aerospace and pressure purposes.1.6For steels and alloys with similar chemical composition, but intended for different applications, see the Bibliography.
