Foreword
This document (EN 10216-5:2013) has been prepared by Technical Committee ECISS/TC 110 “Steel tubes
and fittings for steel tubes”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2014, and conflicting national standards shall be withdrawn at
the latest by June 2014.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 10216-5:2004.
For the list of the most significant technical changes that have been made in this new edition, see Annex B.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This European Standard consists of the following parts, under the general title "Seamless steel tubes for
pressure purposes – Technical delivery conditions":
Part 1: Non-alloy steel tubes with specified room temperature properties;
Part 2: Non-alloy and alloy steel tubes with specified elevated temperature properties;
Part 3: Alloy fine grain steel tubes;
Part 4: Non-alloy and alloy steel tubes with specified low temperature properties;
Part 5: Stainless steel tubes (the present document).
Another European Standard series covering tubes for pressure purposes is:
EN 10217, Welded steel tubes for pressure purposes – Technical delivery conditions.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Scope
This European Standard specifies the technical delivery conditions in two test categories for seamless tubes
of circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless
steel which are intended for pressure and corrosion resisting purposes at room temperature, at low
temperatures or at elevated temperatures.
NOTE
Once this standard is published in the Official Journal of the European Union (OJEU) under Directive
97/23/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 97/23/EC is limited to
technical data of materials in this standard and does not presume adequacy of the material to a specific item of
equipment. Consequently, the assessment of the technical data stated in this material standard against the design
requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied,
needs to be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent
manufacturing processes which may affect properties of the base materials.

Requirements
8.1
General
When supplied in a delivery condition indicated in 7.2.4 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.
8.2
8.2.1
Chemical composition
Cast analysis
The cast analysis reported by the steel manufacturer shall apply and conform to the requirements of Table 2
or Table 3 for austenitic steels and of Table 4 for austenitic-ferritic steels.
Option 3: (see Table 2).
When welding tubes produced in accordance with this part of EN 10216, account should be taken to 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 4: Product analysis for the tubes shall be supplied.
Table 5 specifies the permissible deviation of the product analysis from the specified limits on cast analysis
given in Tables 2, 3 and 4.

If several product analyses are carried out on one cast, and the contents of an individual element determined lie outside the
permissible range of the chemical composition specified for the cast analysis, then it is only allowed to exceed the permissible

Mechanical properties
8.3.1
At room temperature
The mechanical properties of the tubes at room temperature shall conform to the relevant requirements in
Tables 6, 7 and 8 and in Clause 11.
If heat treatments different from, or are additional to, the reference heat treatment, they are to be carried out
after the delivery of the tubes. The purchaser may request, at the time of enquiry and order, additional
mechanical tests on samples that have been given heat treatments different from or additional to, those given
in Tables 6, 7 and 8. The heat treatment of the samples and the mechanical properties to be obtained from
tests on them shall be agreed between the purchaser and the manufacturer at the time of enquiry and order.
Option 5: Additional verification of mechanical properties on samples which have undergone a different or
additional heat treatment shall be carried out.
Option 6: Verification of impact energy shall be carried out at room temperature (see Tables 6, 7 and 8).
Option 7: (see Table 6, footnote a).
Option 8: (see Table 7, footnote a).
8.3.2
8.3.2.1
At elevated temperature
Proof strength
The minimum proof strength Rp0,2 and Rp1,0 values at elevated temperatures are specified in Tables 9, 10 and
11.
Option 9: Proof strength Rp0,2 or Rp1,0 (for austenitic-ferritic steels in Table 11 only Rp0,2 apply) shall be
verified. The verification test temperature shall be agreed at the time of enquiry and order.
Option 10: (see Table 9, footnote a).
8.3.2.2
Creep rupture strength
Annex A gives mean values as preliminary data about creep rupture strength.
NOTE
8.3.3
Steel grades not mentioned in Table A.1 are not intended for use in the creep range.
At low temperature
Impact energy values at specified low temperature shall conform to the requirements in Table 6 and Table 8.
Option 11: Verification of Impact energy at low temperature shall be carried out.

For wall thicknesses greater than 60 mm, the proof strength values are subject to agreement at the time of enquiry and order. Option 10: Agreed proof strength values for wall thicknesses greater than 60 mm
apply.
b
Up to these temperatures, the material should, within 100 000 h, not have changed so as to show susceptibility to intergranular corrosion, when tested in conformity with EN ISO 3651-2. See also Table 6.
