National foreword

This standard has been prepared by Technical Committee ECISS/TC 29 “Steel tubes and fittings for steel tubes” (Secretariat: UNI, Italy).

The responsible German body involved in its preparation was the Normenausschuss Eisen und Stahl (Iron and Steel Standards Committee), Technical Committee 09-04 Rohre aus warmfesten oder kaltz?hen St?hlen.

In Germany, this European Standard is published in a consolidated version incorporating the Amendments A1:2004 and A2:2007.

This standard specifies the technical delivery conditions for seamless tubes of circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel.

Amendments

This standard differs from DIN EN 10216-2:2004-07 as follows:

a) The following new steel grades have been included:

7CrWVMoNb9-6 (1.8201), 7CrMoVTiB10-10 (1.7378), X10CrWMoVNb9-2 (1.4901) and

8.1 General

When supplied in a delivery condition indicated in clause 7.3 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 min or T min the following equations, with all terms in mm, shall apply for the calculation of outside diameter D c, inside diameter d c and wall thickness T c, instead of D, d and T for the

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 agree

d 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 T ≥ 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.
