This document specifies technical delivery conditions for flat and long products of hot rolled weldable fine grain structural steels in the normalized/normalized rolled delivery condition in the grades and qualities given in Tables 1 to 3 (chemical composition) and Tables 4 to 6 (mechanical properties) in thickness ≤ 250 mm. The steels specified in this document are especially intended for use in heavily loaded parts of welded structures such as, bridges, flood gates, storages tanks, water supply tanks, etc., for service at ambient and low temperatures.Cross References:EN ISO 2566-1EN 10279EN 10160EN 10048EN 10168EN 10056-2EN 10020:2000EN 10021EN 10163-2EN 10315EN ISO 14284EN 10308EN 10061EN 1011-2EN 10017EN 10067EN 10051EN 10079EN 10164CR 10320EN 10029EN 10025-1EN 10060EN 10027-2EN 10055EN 10204EN ISO 377EN ISO 14713-2:2009CEN/TR 10347EN 10034EN ISO 6892-1:2016EN ISO 9443EN 10059EN 10056-1EN 10363EN ISO 148-1EN 10163-3EN 10163-1EN 10306EN 10365EN ISO 15350EN 10058EN 10027-1EN 10024EN ISO 1461EN 1090-2EN 10162CEN/TR 10261EN ISO 643EN 1993-1-10All current amendments available at time of purchase are included with the purchase of this document.
