Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 67, Oil and gas industries including lower
carbon energy, Subcommittee SC 6, Process equipment, piping, systems, and related safety, in collaboration
with the European Committee for Standardization (CEN) Technical Committee CEN/TC 12, Oil and gas
industries including lower carbon energy, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This first edition of ISO 13703-2, together with ISO 13703-1 and ISO 13703-3, cancels and replaces
ISO 13703:2000, which has been technically revised. It also incorporates the Technical Corrigendum
ISO 13703:2000/Cor.1:2002.
The main changes compared to the previous edition are as follows:
— deletion of the installation and quality control requirements in Clause 10;
— deletion of former Annex C as requirements are addressed in ASME B31.3;
— addition of material data sheets.
A list of all parts in the ISO 13703 series can be found on the ISO website.

Introduction
Requirements are defined in material datasheets and element datasheets, which can be used for
the specification and procurement of materials for piping systems. Common fabrication, welding,
inspection, examination and testing requirements of piping systems are covered by ISO 13703-3.
Local, national or regional regulations can also affect the specification of piping materials.

Oil and gas industries including lower carbon energy —
Piping systems on offshore platforms and onshore
plants —
Part 2:
Materials
1 Scope
This document provides a set of common supplementary requirements for the most frequently used
materials in upstream oil and gas piping systems.
This document is applicable to offshore and onshore production facilities, processing and gas
liquefaction plants. The materials covered in this document are intended to be used in the following
piping systems services:
— category D, category M, normal and high pressure, according to ASME B31.3;
— sour environments as defined in the ISO 15156 series.
NOTE For the purposes of this document, ANSI/NACE MR0175 is equivalent to the ISO 15156 series, and
ANSI/NACE MR0103 is equivalent to ISO 17945.
This document does not provide guidelines for material selection. The selection of suitable materials for
a specific service including any necessary additional material requirements remains the responsibility
of the end user.
This document does not cover requirements related to:
— sulfide stress cracking (SSC) in corrosive petroleum refining environments included in ISO 17945;
— non-metallic piping systems according to ASME B31.3 or the ISO 14692 series;
— marine piping systems, e.g. ballasting piping system, covered by classification rules;
— subsea production systems;
— downhole equipment;
— transportation pipeline systems, including flowlines, designed in accordance with a recognized
pipeline design code.
Common requirements related to manufacture, inspection and procurement of piping and valve
parts are included in Annex A and Annex B, providing material datasheets and element datasheets,
respectively. These material and element datasheets can be applied for applications other than piping
systems, e.g. pressure vessels and pumps based upon assessment of the end user and conformance with
the selected design code for the relevant equipment. This document is not intended to limit the use of
alternative materials or grades within a referenced material standard. Where the use of alternative
materials/grades are considered appropriate, the end user is responsible for specifying any additional
requirements necessary to meet the design code or specification.

highly alloyed austenitic stainless steel (3.1) alloys with 6 % Mo and PREN ≥ 40,0
3.14
ferritic-austenitic stainless steel type 22Cr duplex
ferritic-austenitic stainless steel alloys with 30,0 ≤ PREN < 40,0 and Cr ≥ 19 % (by mass)
3.15
ferritic-austenitic stainless steel type 25Cr duplex
ferritic-austenitic stainless steel alloys with 40,0 ≤ PREN < 48,0
Note 1 to entry: Stainless steel type 25Cr duplex is often referred to as "super duplex".
3.16
ferritic-austenitic stainless steel type lean duplex
ferritic-austenitic stainless steel alloys with PREN ≥ 28
Note 1 to entry: In this document, stainless steel type lean duplex concerns UNS numbers S32003, S32304 and
S82441.

5 Material and element datasheets
5.1 General
The material datasheets are collated in Annex A. Each MDS defines the requirements that supplement or
amend the referenced material standard or specification. The material shall be delivered in accordance
with the standard specification referenced in the MDS including any additional requirements specified
therein. Unless otherwise specified in the MDS, all the requirements of the referenced standard
specification shall be applied.
MDSs for welded parts specifying acceptance classes give weld joint quality factors ranging from 0,8
to 1,0 according to ASME B31.3. The required class shall be specified on the piping class sheet. The
purchase order shall specify acceptable class for each relevant item.
ISO 13703-2:2023(E)
The element datasheets are included in Annex B. Each EDS defines the requirements for special
processes and parts used in connection with manufacturing and/or assembly of piping and valves.
Processes and parts shall conform with the requirement specified in the EDS in Annex B.
5.2 Numbering system
Each MDS number consists of a one-letter prefix indicating the material type and a three-digit
sequential number. The following one-letter prefixes apply:
— C – carbon steels;
— D – ferritic austenitic stainless steels (duplex stainless steels);
— K – copper-nickel alloy 90-10 and other copper alloys including nickel-aluminium bronze;
— L – nickel alloyed steel;
— M – martensitic stainless steel;
— N – nickel-based alloys;
— R – highly alloyed austenitic stainless steels;
— S – austenitic stainless steels;
— T – titanium;
— V – Cr and Cr-Mo alloyed steels;
— X – high strength low alloy steels.
The supplementary suffix “S” is used to designate a material delivered in accordance with the MDS plus
the supplementary requirements for sour service but excluding HIC testing.
