For these steel grades it may be necessary in the case of wall thickness T above 10 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”.
8 Requirements
8.1 General
When supplied in a delivery condition indicated in 7.2 and inspected in accordance with Clauses 9, 10
and 11, the tubes shall conform to the requirements of this Part of EN 10216.
In addition, the general technical delivery requirements specified in EN 10021 shall apply.
Tubes shall be suitable for hot and cold bending provided the bending is carried out in an appropriate
manner.
When tubes are specified in the order by d, d or T the following formulae, with all terms in mm,
min min
shall apply for the calculation of outside diameter D , inside diameter d and wall thickness T , instead of

8.2 Chemical composition
8.2.1 Cast analysis
The cast analysis reported by the steel producer shall apply and conform to the requirements of Table
2.
When welding tubes produced in accordance with this Part of this EN 10216, account should be taken of
the fact that the behaviour of the steel during and after welding is dependent not only on the steel, but
also on the applied heat treatment and the conditions of preparing for and carrying out the welding.
8.2.2 Product analysis
Option 3: Product analysis for the tubes shall be supplied.
Table 3 specifies the permissible deviations of the product analysis from the specified limits on cast
analysis given in Table 2.
