6 Manufacturing conditions
6.1 General
If not stated otherwise, the manufacturing procedure is at the discretion of the manufacturer.
6.2 Treatment conditionsThe wire shall be specified in one of the following conditions, depending on the structure:
— Condition +A: The wire is annealed as the final heat treatment. Note that this material might be
slightly deformed by straightening, cold work, size control, or finish. This will result in a slight
increase of the tensile strength.— Condition +AT: The wire is solution annealed as the final heat treatment. Note that this material
might be slightly deformed by straightening, cold work, size control, or finish. This will result in a
slight increase of the tensile strength.— Condition +C: The wire is hard drawn as the last operation, in order to achieve higher strength.
6.3 Surface finishIf not specified otherwise, the surface finish of the wire is one of the following, depending on previous
processing steps.6.3.1 Cold drawn
This is the natural finish resulting from the drawing to final size, generally with cold-drawing lubricant
left on. The finish will be duller for dry-drawn wire or shinier for wire that is wet drawn. Fine sizes are
commonly wet drawn, whereas coarser sizes are commonly dry drawn. Special bright finishes, lubricant
removal, etc. required for special end-use shall be negotiated with the manufacturer.
© ISO 2014 – All rights reserved 3---------------------- Page: 7 ----------------------
ISO 16143-3:2014(E)
6.3.2 Annealed
This is a dull matt appearance, necessarily associated with the dead soft condition of annealed wire
when no final drawing is permitted. With an additional surface treatment, a bright appearance can be
realized.6.3.3 Polished finish
This is a smooth and uniform bright finish of cold-processed (+C) material obtained by mechanical
smoothing, burnishing, abrading, or grinding.7 Requirements
7.1 Manufacturing process
The steelmaking process for products according to this part of ISO 16143 shall be in accordance with
ISO 4955 and ISO 16143-2. The wire processing, insofar as it is not specified in this part of ISO 16143 or
agreed between the parties, shall be at the discretion of the wire drawer.7.2 Delivery condition
The product shall be supplied as described in Clause 6 and agreed in the order.
7.3 Chemical analysis
7.3.1 Cast analysis
The chemical composition requirements given in Table 1 apply with respect to the chemical composition
of the cast analysis.7.3.2 Product analysis
The product analysis can deviate from the limiting values for the cast analysis given in Table 1 by the
values listed in Table 2.7.4 Mechanical properties
7.4.1 Mechanical properties for annealed wire
The tensile strength and elongation shall satisfy the requirements of Table 3. It specifies the mechanical
properties at room temperature in the annealed condition. For austenitic, austenitic-ferritic, and
precipitiation-hardening steels, the wire is in the condition +AT; for ferritic and martensitic steels, this
is in the condition +A.7.4.2 Mechanical properties of hard-drawn wire
This wire is in condition +C The tensile strength will depend on the degree of work hardening, the
specific type of steel, and the processing of the material. The tensile strength is specified by a minimum
and maximum. Not all the tensile strength levels listed in Table 4 can be achieved for all steel grades.
Therefore, the required tensile-strength level shall be agreed between the manufacturer and the
purchaser at the time of ordering.Table 4 gives an overview of the standardized tensile-strength levels and the corresponding minimum
and maximum.4 © ISO 2014 – All rights reserved

ISO 16143-3:2014(E)
7.5 Tolerances on dimensions
For round wire, the purchaser shall specify normal tolerance (N) or restricted tolerance (R), as defined
in Table 5. For non-round wire, tolerances shall be agreed upon at the time of ordering.
The out-of-roundness is the difference between the largest and the smallest diameter in the same cross
section of the wire. The cross section shall be perpendicular to the longitudinal wire axis. The out-of-
roundness shall not exceed half the total diameter tolerance specified for coils.
8 Inspection, testing, and conformance of products8.1 General
The manufacturer shall carry out appropriate process control, inspection, and testing to ensure that the
delivery complies with the requirements of the order.This includes the following:
— a suitable frequency of verification of the dimensions of the products;
— an adequate intensity of visual examination of the surface quality of the products;
— an appropriate frequency and type of test to ensure that the correct grade of steel is delivered.
The nature and frequency of these verifications, examinations, and tests are determined by the
manufacturer, based on the degree of consistency that has been determined by the evidence of his
quality system. In view of this, verifications by specific tests for these requirements are not necessary,
unless otherwise agreed.8.2 Inspection and testing procedures and types of inspection documents
8.2.1 Products complying with this part of ISO 16143 shall be ordered and delivered with one of the
inspection documents as specified in ISO 10474. The type of document shall be agreed upon at the time
of enquiry and order. If the order does not contain any specification of this type, a test report 2.2 shall be
issued.8.2.2 If, in accordance with the agreements made at the time of ordering, a test report is to be provided,
this shall covera) the statement that the material complies with the requirements of the order and
b) the results of the cast analysis for all elements specified for the type of steel supplied.
8.2.3 If, in accordance with the agreements in the order, an inspection certificate 3.1 or 3.2 of ISO 10474
is to be provided, the specific inspections and tests described in 8.3 shall be carried out and their results
shall be certified in the document.In addition to 8.2.2, the document shall cover
a) the results of the tests of Table 6 and
b) the results of any optional test or inspection agreed when ordering.

6 Manufacturing conditions
6.1 General
If not stated otherwise, the manufacturing procedure is at the discretion of the manufacturer.
6.2 Treatment conditionsThe wire shall be specified in one of the following conditions, depending on the structure.
Condition +A: The wire is annealed as final heat treatment. Note that this material may be slightly deformed by
straightening, cold work, size control or finish. This will result in a slight increase of the tensile strength.
Condition +AT: The wire is solution annealed as final heat treatment. Note that this material may be slightly
deformed by straightening, cold work, size control or finish. This will result in a slight increase of the tensile
strength.Condition +C: The wire is hard drawn as the last operation, in order to achieve higher strength.
6.3 Surface finishIf not specified otherwise, the surface finish of the wire is one of the following, depending on previous
processing steps.© ISO 2012 – All rights reserved 3
---------------------- Page: 7 ----------------------
ISO/DIS 16143-3
6.3.1 Cold drawn
This is the natural finish resulting from the drawing to final size, generally with cold-drawing lubricant left on.
The finish will be duller for dry drawn wire or shinier for wire that is wet drawn. Fine sizes are commonly wet
drawn, whereas coarser sizes are commonly dry drawn. Special bright finishes, lubricant removal etc. required
for special end-use must be negotiated with the manufacturer.6.3.2 Annealed
A dull matt appearance, necessarily associated with the dead soft condition of annealed wire when no final
drawing is permitted. With an additional surface treatment, a bright appearance can be realized.
6.3.3 Polished finishA smooth and uniform bright finish of cold processed (+C) material obtained by mechanical smoothing,
burnishing, abrading or grinding.7 Requirements
7.1 Manufacturing process
The steel-making process for products according to this part of ISO 16143 shall be in accordance with
ISO 4955 and ISO 16143-2. The wire processing, insofar as it is not specified in this part of ISO 16143 or
agreed between the parties, shall be at the discretion of the wire drawer.7.2 Delivery condition
The product shall be supplied as described in Clause 6 and agreed in the order.
7.3 Chemical analysis
7.3.1 Cast analysis
The chemical composition requirements given in Table 1 apply with respect to the chemical composition of the
cast analysis.7.3.2 Product analysis
The product analysis may deviate from the limiting values for the cast analysis given in Table 1 by the values
listed in Table 2.NOTE It is under discussion to change the deviations to the values according to ASTM.
7.4 Mechanical properties7.4.1 Mechanical properties for annealed wire
The tensile strength and elongation shall satisfy the requirements of Table 3. It specifies the mechanical
properties at room temperature in the annealed condition. For austenitic, austenitic-ferritic and precipitiation-
hardening steels, the wire is in the condition +AT, for ferritic and martensitic steels, this is in the condition +A.
7.4.2 Mechanical properties of hard-drawn wireThis wire is in condition (+C). The tensile strength will depend on the degree of work hardening, the specific
type of steel and the processing of the material. The tensile strength is specified by a minimum and maximum.
4 © ISO 2012 – All rights reserved---------------------- Page: 8 ----------------------
ISO/DIS 16143-3
Not all the tensile strength levels listed in Table 4 can be achieved for all steel grades. Therefore, the required
tensile-strength level shall be agreed between the manufacturer and the purchaser at the time of ordering.
Table 4 gives an overview of the standardized tensile-strength levels and the corresponding minimum and
maximum.7.5 Tolerances on dimension
For round wire, the purchaser shall specify normal tolerance (N) or restricted tolerance (R), as defined in
Table 5. For non-round wire, tolerances shall be agreed upon at the time of ordering.
The out of roundness is the difference between the largest and the smallest diameter in the same
cross-section of the wire. The cross-section shall be perpendicular to the longitudinal wire axis. The
out-of-roundness shall not exceed half the total diameter tolerance specified for coils.
8 Inspection, testing and conformance of products8.1 General
The manufacturer shall carry out appropriate process control, inspection and testing to assure himself that the
delivery complies with the requirements of the order.This includes the following:
a suitable frequency of verification of the dimensions of the products;
an adequate intensity of visual examination of the surface quality of the products;
an appropriate frequency and type of test to ensure that the correct grade of steel is delivered.
The nature and frequency of these verifications, examinations and tests are determined by the manufacturer,
based on the degree of consistency that has been determined by the evidence of his quality system. In view of
this, verifications by specific tests for these requirements are not necessary, unless otherwise agreed.
8.2 Inspection and testing procedures and types of inspection documents8.2.1 Products complying with this International Standard shall be ordered and delivered with one of the
inspection documents as specified in ISO 10474. The type of document shall be agreed upon at the time of
enquiry and order. If the order does not contain any specification of this type, a test report 2.2 shall be issued.
8.2.2 If, in accordance with the agreements made at the time of ordering, a test report is to be provided, this
shall cover:a) the statement that the material complies with the requirements of the order;
b) the results of the cast analysis for all elements specified for the type of steel supplied.
8.2.3 If, in accordance with the agreements in the order, an inspection certificate 3.1 or 3.2 of ISO 10474 is
to be provided, the specific inspections and tests described in 8.3 shall be carried out and their results shall be
certified in the document.In addition to 8.2.2, the document shall cover:
a) the results of the tests of Table 6;
b) the results of any optional test or inspection agreed when ordering.
