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 “.
d
For these steel grades it may be necessary in case of wall thickness T above 16 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
Elements not included in this Table shall not be intentionally added to the steel without the agreement of the purchaser, except for elements which may be added for finishing the cast. All
appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steel making process.
b
This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements which shall be reported. When using titanium, the producer shall verify
that (Al+Ti/2)≥0,020%
c
Option 2: In order to facilitate subsequent forming operations, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply
d
The content of these elements need not to be reported unless intentionally added to the cast.
e
For wall thickness ≥ 30 mm the carbon content may be increased by 0,02 % for cast and product analysis.
f
The upper carbon value of 0,23 % shall not be exceeded for product analysis.
