ISO 9444-2:2009(E)
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 9444-2 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and
alloy steels.
This first edition of ISO 9444-2 cancels and replaces the second edition of ISO 9444:2002, the contents of
which has been technically revised and separated into two parts.
ISO 9444 consists of the following parts, under the general title Continuously hot-rolled stainless steel —
Tolerances on dimensions and form:
⎯ Part 1: Narrow strip and cut lengths
⎯ Part 2: Wide strip and sheet/plate

INTERNATIONAL STANDARD ISO 9444-2:2009(E)

Continuously hot-rolled stainless steel — Tolerances on
dimensions and form —
Part 2:
Wide strip and sheet/plate
1 Scope
This part of ISO 9444 specifies the tolerances on dimensions and form for continuously hot-rolled stainless
steel wide strip in actual widths from 600 mm to 2 500 mm and for sheet/plate cut from such strip.
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 6929:1987, Steel products — Definitions and classification
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6929 and the following apply.
3.1
hot-rolled sheet/plate
flat rolled product, the edges being allowed to deform freely, supplied flat and generally square or rectangular,
but also in any other shape, for example circular or according to the design sketch; the edges are as-rolled or
sheared or flame-cut or chamfered
NOTE 1 The product may also be delivered precurved.
NOTE 2 Hot-rolled sheet/plate may be produced:
a) directly rolled on a reversing mill, or by cutting from a parent plate rolled on a reversing mill;
b) by cutting from hot-rolled strip rolled on a continuous mill.
NOTE 3 Reversing-mill plate is known generally as “quarto-plate”.
Continuous-mill sheet/plate is known generally as “hot-rolled sheet/plate”.
NOTE 4 Where further subdivision is required to be made on the basis of thickness for statistical purposes, the
following is recommended:
a) sheet: thickness less than 3 mm (except electrical sheet);
b) plate: thickness equal to or greater than 3 mm.
NOTE 5 Adapted from ISO 6929:1987, definition 6.2.6.2.2.2.
ISO 9444-2:2009(E)
3.2
hot-rolled strip
hot-rolled flat product which immediately after the final rolling pass or after pickling or annealing is wound into
laps so as to form a coil
NOTE 1 Hot-rolled strip as-rolled has slightly convex edges, but it may also be supplied with sheared edges or be
obtained by slitting wider hot-rolled strip.
[ISO 6929:1987, definition 6.2.6.2.2.3.1]
NOTE 2 According to its actual width, including hot-rolled slit strips irrespective of the rolling width, hot-rolled strip is
classified as
⎯ hot-rolled wide strip: strip of a width equal to or greater than 600 mm, or
⎯ hot-rolled narrow strip: strip of a width less than 600 mm.
After decoiling and cutting to length, hot-rolled narrow strip may be supplied as cut lengths.
