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 5000 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 12, Continuous mill flat
rolled products.
This third edition cancels and replaces the second edition (ISO 5000:1993), which has been technically
revised.

INTERNATIONAL STANDARD ISO 5000:2005(E)

Continuous hot-dip aluminium-silicon-coated cold-reduced
carbon steel sheet of commercial and drawing qualities
1 Scope
This International Standard specifies the characteristics of cold-reduced carbon steel sheet of commercial and
drawing qualities coated by a continuous hot-dip aluminium-silicon alloy coating process.
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 6892, Metallic materials — Tensile testing at ambient temperature
ISO 7438, Metallic materials — Bend test
ISO 16160, Continuously hot-rolled steel sheet products — Dimensional and shape tolerances
ISO 16162, Continuously cold-rolled steel sheet products — Dimensional and shape tolerances
ISO 16163, Continuously hot-dipped coated steel sheet products — Dimensional and shape tolerances
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
skin pass
light cold rolling of the product.
NOTE The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the
surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition known as stretcher
strain (Luder’s Lines) or fluting during the fabrication of finished parts. The skin pass also controls and improves flatness.
Some increase in hardness and some loss of ductility will result from skin passing.
3.2
strain ageing
change in steel properties with the passage of time
NOTE Strain ageing may result in surface imperfections such as stretcher strain marks (Luder’s Lines), fluting when
the steel is formed, and a deterioration in ductility. To avoid these adverse outcomes, the period between final processing
at the producing mill and fabrication needs to be kept to a minimum. Rotation of stock, by using the oldest material first, is
important. Effective roller-levelling immediately prior to fabrication can achieve reasonable freedom from stretcher strain
marks.

4 Requirements
4.1 Steelmaking and processing
4.1.1 General
The processes used in making the steel and in manufacturing aluminium-silicon-coated sheet are left to the
discretion of the manufacturer. When requested, the purchaser shall be informed of the steelmaking process
being used. Steel sheet is produced in a number of qualities, coating mass, grades, surface treatments and
conditions designed to be compatible with differing application requirements.
Aluminium-silicon-coated steel sheet is available in several fabrication qualities:
a) commercial: intended for general fabricating purposes where sheet is used in the flat, or for bending or
moderate forming;
b) drawing: intended for fabricating parts where drawing or severe forming may be involved;
c) deep-drawing: intended for parts where severe drawing or forming is involved;
d) deep-drawing aluminium-killed (non-ageing): intended for fabricating parts where particularly severe
drawing or forming may be involved or essential freedom from ageing is required;
e) extra-deep-drawing (stabilized interstitial free): intended for applications requiring interstitial-free steel (IF)
which is non-ageing and has maximum formability.
4.1.2 Sheet dimensions
Aluminium-silicon-coated steel sheet is produced in thicknesses from 0,40 mm to 3,0 mm inclusive and in
widths of 600 mm to 1 500 mm in coils and cut lengths. Aluminium-silicon-coated sheet less than 600 mm
wide may be slit from wide sheet and will be considered as sheet.
The thickness of aluminium-silicon coated steel sheet may be specified as
a) a combination of the base metal and metallic coating, or
b) base metal alone.
Information shall be supplied by the purchaser indicating which method of specifying thickness is appropriate
for the order. If the purchaser provides no information, the thickness as a combination of the base metal and
coating will be provided. Annex A describes the requirements for specifying the thickness as base metal alone.
4.1.3 Ordering conditions
Aluminium-silicon-coated steel sheet may be ordered in one of two conditions:
a) condition A: steel ordered to satisfy mechanical property requirements;
b) condition B: steel ordered to make an identified part.
4.2 Chemical composition
The chemical composition of the steel (heat analysis) shall conform to the requirements of Tables 1 and 2.

---------------------- Page: 6 ----------------------
ISO 5000:2005(E)
A verification analysis (product analysis) may be made by the purchaser to verify the specified analysis of the
semi-finished or finished steel, and shall take into account any normal heterogeneity. Non-killed steels such as
rimmed or capped are not technologically suited for verification analysis. The tolerances for verification
analysis (product analysis) are given in Table 3.

For interstitial-free steels only, the values of 0,15 % maximum for titanium, 0,10 % maximum for niobium and vanadium are
acceptable to ensure that the carbon and nitrogen are fully stabilized.
By agreement, the levels of manganese, phosphorus, sulfur and titanium may be adjusted.

Each of the elements listed in this table shall be included in the report of the heat analysis. When the amount of copper,
nickel, chromium or molybdenum present is less than 0,02 % (mass fraction), the analysis result may be reported as
< 0,02 %.
a
The sum of copper, nickel, chromium and molybdenum shall not exceed 0,50 % (mass fraction) on heat analysis.
When one or more of these elements is specified, the sum does not apply, in which case only the individual limits on the
remaining elements apply.
b
The sum of chromium and molybdenum shall not exceed 0,16 % (mass fraction) on heat analysis. When one or more
of these elements is specified, the sum does not apply, in which case, only the individual limits on the remaining elements
apply.
c
Heat analysis greater than 0,008 % (mass fraction) may be supplied after agreement between producer and
consumer.

product analysis values are within these tolerances: C 0,15, Mn 0,53, P 0,05, S 0,05.
