^a +N = Normalising, +NT = Normalising + Tempering, +QT = Quenching + Tempering (air or liquid), +I = Isothermal Annealing.

^b Normalising includes Normalising Forming.

^c For these steel grades it may be necessary in the case of wall thickness T above 25 mm or T/D > 0,15 to apply quenching and tempering in order to achieve the intended structure and material properties . The decision shall be left to the discretion of the manufacturer but shall be stated to the customer at the time of enquiry and order. Steel tubes treated in such a way shall be designated by the steel name supplemented by the symbol +QT .

^a Element not included in this table shall not be intensionally to the steel without the agreenent of the purchaser, except for elements which may be added for finishing the cast. All appropriate shall be taken to prevent the addition of unsirable elements from scrap or other materialss used in the steel making process.
^b This requirement is not applicable provided steel contains a sufficient amont of then nitrogen binding elements which shall be reported. When using titanium, the producer shall verify that (Al+Ti)≥0.02%
^cOption 2: In order to faciliate subsequent forming operations, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply
^dThe content of these elements need not to be reported unless intensionally added to the cast.
^eFor wall thickness≥30mm the carbon content may be increased by 0.02% for the cast and product analysis.
The upper carbon value of 0.23% shall not be exceeded for product analysis.

After testing, the test piece shall be free from cracks or breaks. However, slight incipient cracks at its edges shall not be regarded as justification for rejection.
Ring tensile test
The test shall be carried out in accordance with EN 10237. The tube section shall be subjected to strain in the circumferential direction until fracture occurs. After fracture the test pieces shall not show any visible cracks without the use of magnifying aids (excluding the fracture point).
Drift expanding test
The test shall be carried out in accordance with EN 10234. The tube section shall be expanded with a 60° conical tool until the percentage increase in outside diameter shown

^aThe values listed in the Table are values suggested by ECCC (1) and are average values from scatter range determined from existing data which will be assessed from time to time after test results are available and corrected if necessary. The values for the steel grades 14MoV6-3 and X10CrMoVNb9-1 have been obtained by new evaluation. For the remaining steel grades the values were obtained from creep rupture strength values given in national and international standards
^b The creep rupture strength values given up to the elevated temperature listed in the Table, do not mean that the steels can be used in continuous duty up to the these temperatures. A governing factor is the total stress during operation.
^c For the creep rupture strength values indicated in the Table the extrapolation times are always less than a factor of three unless indicated by an asterisk (*).
