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.

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.
