EN 10025-5:2004 (E) 5 1 Scope Part 5 of this document, in addition to part 1, specifies requirements for flat and long products of hot rolled st
28、eels with improved atmospheric corrosion resistance in the grades and qualities given in Tables 2 and 3 (chemical composition) and Tables 4 and 5 (mechanical properties) in the usual delivery conditions as given in 6.3. The thicknesses in which products of the steel grades and qualities specified in
29、 this document may be supplied are given in Table 1. In addition to EN 10025-1:2004 the steels specified in this document are especially intended for use in welded, bolted and riveted components which shall have enhanced resistance to atmospheric corrosion, for service at ambient temperatures (subje
30、ct to the restrictions described in 7.4.1). The steels specified in this Part 5 are not intended to be heat treated except products delivered in the delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can b

EN 10025-
43、5:2004 (E) 7 3.1 normalizing rolling rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after normalizin
44、g The abbreviated form of this delivery condition is +N. NOTE In international publications for both the normalizing rolling, as well as the thermomechanical rolling, the expression “controlled rolling“ may be found. However in view of the different applicability of the products a distinction of the
45、 terms is necessary. 3.2 as-rolled delivery condition without any special rolling and/or heat treatment condition The abbreviated form of this delivery condition is +AR. 3.3 steel with improved atmospheric corrosion resistance steel in which a certain number of alloying elements, such as P, Cu, Cr,
46、Ni, Mo, has been added in order to increase its resistance to atmospheric corrosion, by forming an auto-protective oxide layer on the base metal under the influence of weather conditions NOTE 1 Steel with improved atmospheric corrosion resistance is often called weathering steel. NOTE 2 Additional i

48、es and qualities This document specifies the steel grades S235 and S355 (see Table 5), which differ in their mechanical properties. The steel grades may be supplied in qualities J0, J2 and K2. The qualities differ in specified impact energy requirements. Grade S355 is subdivided into the classes W a
49、nd WP, which differ mainly in their carbon and phosphorus contents (see Tables 2 and 3) and availability (see Table 1). 4.2 Designation 4.2.1 The designation shall be in accordance with EN 10025-1.
