Description Welded and cold sized +CR1
Normally not heat treated, but suitable for final annealing. b +CR2
Not intended for heat treatment after the welding and sizing. c Soft annealed +A After welding and sizing the tubes are annealed in a controlled atmosphere. Normalized +N After welding and sizing the tubes are normalized in a controlled atmosphere. a In accordance with EN 10027-1. b After annealing or normalizing, the resulting mechanical properties meet the requirements specified in Table 4 for the delivery condition +A or +N, respectively.
c If further heat treatment is applied, the resulting mechanical properties may be outside the specified
requirements. 8 Requirements 8.1 General The tubes, when supplied in a delivery condition indicated in Table 1 and inspected in accordance with Clauses 9, 10 and 11, shall comply with the requirements of this document. In addition, the general technical delivery requirements specified in EN 10021 apply. 8.2 Chemical composition The cast analysis reported by the steel producer shall apply and comply with the requirements of Table 2. A steel grade not specified in this document may be specified (see option 1). Option 1:
A steel grade not specified in this document with a maximum total content of alloying elements of
5 % and agreed chemical composition, mechanical properties and delivery condition, is specified. NOTE When subsequently welding tubes produced in accordance with this document, account should be taken of the fact that the behaviour of the steel during and after welding is dependent not only on the steel composition and the delivery condition, but also on the conditions of preparing for and carrying out the welding. Option 2: The composition of the specified steel grade shall be such that it is suitable for hot-dip galvanizing (see e.g. EN ISO 1461 for guidance). SIST EN 10305-3:2010
