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 9444-1 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 4, Heat treatable and

alloy steels.

This first edition of ISO 9444-1 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 9444-1:2009(E)
Continuously hot-rolled stainless steel — Tolerances on
dimensions and form —
Part 1:
Narrow strip and cut lengths
1 Scope

This part of ISO 9444 specifies the tolerances on dimensions and form for continuously hot-rolled stainless

steel narrow strip in actual widths of less than 600 mm. It also applies to cut lengths taken 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 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.

4 Information to be supplied by the purchaser

4.1 It shall be the responsibility of the purchaser to specify all requirements that are necessary for products

under this specification. Such requirements to be considered include, in the order listed, but not limited to, the

following:
a) the type of delivery [see 5.1 a) and 5.1 b)];
b) the number of this part of ISO 9444, i.e. ISO 9444-1;
c) the thickness, in millimetres (if necessary, accurate to two decimal places);

d) whether normal tolerances or fine tolerances (F) (see Table 1) of thickness are required;

e) the width, in millimetres;
f) the condition of the edges (M = mill edges, T = trimmed edges);

g) for narrow strip [see 5.1 a)], the condition of the ends [R = mill (rolled) ends, C = cropped ends];

h) for cut lengths, the length, in millimetres;
i) any special delivery condition (see 5.2).

EXAMPLE 1 Hot-rolled narrow strip in accordance with this International Standard, with a specified thickness of

2,5 mm, a specified width of 500 mm, with trimmed edges (T) and cropped ends (C):

Hot-rolled narrow strip ISO 9444-1 – 2,5 × 500T-C

EXAMPLE 2 Hot-rolled cut lengths in accordance with this International Standard with a specified thickness of 3,0 mm,

fine thickness tolerance (F), a specified width of 100 mm, with trimmed edges (T) and length 1 500 mm:

Hot-rolled cut lengths ISO 9444-1 – 3,0F × 100T × 1500

4.2 In the absence of information in the order concerning special requirements for tolerances on dimension

and shape [see 4.1 c) to 4.1 i)], hot-rolled products covered by this part of ISO 9444 will be delivered in

accordance with the basic specificat
