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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15156-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore strcutures
for petroleum and natural gas industries.
ISO 15156 consists of the following parts, under the general title Petroleum and natural gas industries —
Materials for use in H S-containing environments in oil and gas production:
Part 1: General principles for selection of cracking-resistant materials
Part 2: Cracking-resistant carbon and low alloy steels, and the use of cast irons
Part 3: Cracking-resistant CRAs (corrosion-resistant alloys) and other alloys

ISO 15156-2:2003(E)
Introduction
The consequences of sudden failures of metallic oil and gas field components, associated with their exposure
to H S-containing production fluids, led to the preparation of the first edition of NACE MR0175, which was
published in 1975 by the National Association of Corrosion Engineers, now known as NACE International.
The original and subsequent editions of NACE MR0175 established limits of H S partial pressure above which
precautions against sulfide stress-cracking (SSC) were always considered necessary. They also provided
guidance for the selection and specification of SSC-resistant materials when the H S thresholds were
exceeded. In more recent editions, NACE MR0175 has also provided application limits for some
corrosion-resistant alloys, in terms of environmental composition and pH, temperature and H S partial
pressures. NACE MR0175 is complemented by NACE TM0177-96 and NACE TM0284 test methods.
In separate developments, the European Federation of Corrosion issued EFC Publication 16 in 1995 and EFC
Publication 17 in 1996. These documents are generally complementary to those of NACE though they differ in
scope and detail.
This part of ISO 15156 utilizes the above sources to provide requirements and recommendations for materials
qualification and selection for application in environments containing wet H S in oil and gas production
systems.
Changes will be incorporated into this part of ISO 15156 by amendment or revision in accordance with
Interpretation and maintenance of ISO 15156 by ISO/TC 67/WG 7, copies of which can be obtained from the
ISO/TC 67 Secretariat. Experts from both NACE and EFC are members of ISO/TC 67/WG 7.

Petroleum and natural gas industries — Materials for use in
H S-containing environments in oil and gas production —
Part 2:
Cracking-resistant carbon and low alloy steels, and the use of
cast irons
WARNING — Carbon and low alloy steels and cast irons selected using this part of ISO 15156 are
resistant to cracking in defined H S-containing environments in oil and gas production but not
necessarily immune to cracking under all service conditions. It is the equipment user's responsibility
to select the carbon and low alloy steels and cast irons suitable for the intended service.
1 Scope
This part of ISO 15156 gives requirements and recommendations for the selection and qualification of carbon
and low alloy steels for service in equipment, used in oil and natural gas production and natural gas treatment
plants in H S-containing environments, whose failure could pose a risk to the health and safety of the public
and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the
equipment itself. It supplements, but does not replace, the materials’ requirements of the appropriate design
codes, standards or regulations.
This part of ISO 15156 addresses the resistance of these steels to damage that may be caused by sulfide
stress-cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and
soft-zone cracking (SZC).
This part of ISO 15156 also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and
its possible development into stepwise cracking (SWC).
This part of ISO 15156 is only concerned with cracking. Loss of material by general (mass loss) or localized
corrosion is not addressed.
Table 1 provides a non-exhaustive list of equipment to which this part of ISO 15156 is applicable, including
permitted exclusions.
This part of ISO 15156 applies to the qualification and selection of materials for equipment designed and
constructed using conventional elastic design criteria. For designs utilizing plastic criteria (e.g. strain-based
and limit-state designs), see ISO 15156-1:2001, Clause 5.
Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast
irons.
This part of ISO 15156 is not necessarily suitable for application to equipment used in refining or downstream
processes and equipment.
