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 14737 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 11, Steel castings.

INTERNATIONAL STANDARD ISO 14737:2003(E)

Cast non-alloy and low alloy steels for general applications
1 Scope
This International Standard specifies requirements for cast non-alloy and low alloy steel grades for general
applications.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 148:1983, Steel — Charpy impact test (V-notch)
ISO 4990:1986, Steel castings — General technical delivery requirements
ISO 6892:1998, Metallic materials — Tensile testing at ambient temperature
3 General conditions for delivery
Steel castings supplied in accordance with this International Standard shall conform to the applicable
requirements of ISO 4990, including the supplementary requirements that are indicated in the inquiry and
purchase order.
4 Chemical composition
The chemical composition shall conform to the values given in Table 1.
5 Heat treatment
The type of heat treatment is left to the discretion of the manufacturer unless otherwise agreed upon at the
time of inquiry and order. The information for heat treatment described in Table 2 is for information only.
6 Mechanical properties
Mechanical properties are given in Table 2 and shall be subject to an agreement at the time of inquiry and
order.
Unless otherwise specified (see ISO 4990) the thickness of the test block shall be 28 mm minimum.
Properties at thicknesses greater than the maximum thickness in Table 2 may be lower and are subject to an
agreement between manufacturer and purchaser.

7 Test methods
7.1 Tensile testing shall be performed in accordance with ISO 6892.
7.2 Impact testing shall be performed in accordance with ISO 148.
8 Supplementary requirements
This international standard also specifies a group of supplementary requirements, which may be applied to
steel castings. These requirements are provided for use when additional testing or inspection is desired and
apply only when individually specified by the purchaser.
A list of supplementary requirements which may be used at the option of the purchaser is given in ISO 4990
and in Annex A.
