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 10384 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 12, Continuous mill
flat rolled products.
This fourth edition cancels and replaces the third edition (ISO 10384:2008), which has been
technically revised.

INTERNATIONAL STANDARD ISO 10384:2012(E)
Hot-rolled carbon steel sheet as defined by chemical
composition
1 Scope
This International Standard applies to hot-rolled carbon steel sheet as defined by chemical composition.
The product is generally used in the heat-treated condition after hot or cold working, press forming
or cutting by the customer. For example, the product is used for general machinery such as sprocket
wheels, chain links, washers, knife blades and agricultural implements.
NOTE 1 Hot-rolled sheet up to but not including 3 mm in thickness is commonly known as “sheet”. Hot-rolled
sheet 3 mm and over in thickness is commonly known as either “sheet” or “plate”.
NOTE 2 Steel sheet that is to be subjected to subsequent rerolling is not covered by this International Standard.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the reference document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
hot-rolled steel sheet
product obtained by rolling heated steel through a continuous hot strip mill or other hot rolling processes
that produce a coiled product to the required sheet thickness and tolerances
Note 1 to entry: The product has a surface covered with oxide or scale resulting from the hot rolling operation.
3.2
hot-rolled descaled steel sheet
hot-rolled steel sheet from which oxide or scale has been removed, usually by pickling in an acid solution
Note 1 to entry: Descaling may also be performed by appropriate mechanical means.
3.3
mill edge
normal edge without any definite contour produced in hot rolling
Note 1 to entry: Mill edges can contain some irregularities such as cracked or torn edges or thin (feathered) edges.
3.4
sheared edge
normal edge obtained by shearing, slitting or trimming a mill edge product
Note 1 to entry: Normal processing does not necessarily provide a definite positioning of the slitting burr.
4 Thickness
4.1 Hot-rolled carbon steel sheet based on chemical composition is manufactured from killed steel
of the chemical compositions listed in Table 1. It is usually produced in the range of thicknesses from
0,8 mm to 12,5 mm inclusive, and in widths of 600 mm and over, in coils and cut lengths.
4.2 Hot-rolled carbon steel sheet less than 600 mm wide may be slit from wide sheet and will be
considered as sheet.
5 Conditions of manufacture
5.1 Steelmaking
Unless otherwise agreed by the interested parties, the processes used in making the steel and in
manufacturing hot-rolled sheet are left to the discretion of the manufacturer. On request, the purchaser
shall be informed of the steelmaking process used.
5.2 Chemical composition
The chemical composition (heat analysis) shall comply with the
