ASTM A905-19

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: A905 − 04 (Reapproved 2017) A905 − 19
Standard Specification for
Steel Wire, Pressure Vessel Winding
This standard is issued under the fixed designation A905; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This specification covers requirements for a high strength drawn and cold rolled steel wire in two strength classes, with
rectangular cross section, and round mill edge. This wire is intended for prestressed vessel and press frame windings.
1.2 The values stated in either inch-pound units or SI (metric) units are to be regarded separately as standards. Within the text
and tables, the SI units are shown in parentheses. The values stated in each system are not exact equivalents. Therefore, each
system must be used independent of the other. Combining values from the two systems may result in nonconformance with the
specification.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1.5 Packaging (see Section 11),
3.1.6 Cast or heat analysis report (see Section 5),
3.1.7 Number of certification or test reports required (see Section 10),
3.1.8 ASTM designation and year of issue, and
3.1.9 Supplementary requirements, if any.
4. Material and Manufacture
4.1 The steel shall be produced by any of the following primary processes: (1) basic oxygen, and (2) electric furnace or vacuum
induction (VIM). The primary melting may incorporate separate degassing or refining and may be followed by secondary melting
by the electrode slag process (ESR) or the vacuum arc remelting process (VAR).
4.1.1 The steel may be ingot cast or continuously cast.
4.2 The finished wire shall be free from detrimental pipe and undue segregation.
4.3 The wire shall be cold drawn or cold rolled, or both, to produce the desired mechanical properties and dimensions after
subjecting it to the patenting treatment.
4.4 The width to thickness ratio of the wire cross section shall not exceed 8.
5. Chemical Composition
5.1 The steel shall conform to the requirements for chemical composition prescribed in Table 1.
5.2 Heat Analysis—Each heat of steel shall be analyzed by the manufacturer to determine the percentage of elements prescribed
in Table 1. This analysis shall be made from a test specimen preferably taken during the pouring of the heat. When requested, this
shall be reported to the purchaser and shall conform to the requirements of Table 1.
5.3 Product Analysis—An analysis may be made by the purchaser from finished wire representing each heat of steel. The
chemical composition thus determined, as to elements required or restricted, shall conform to the product analysis requirements
specified in Table 10 of Specification A510A510/A510M or A510M.
5.4 For referee purposes, Test Methods Methods, Practices, and Terminology E30A751 shall be used.
6. Mechanical Requirements
6.1 Tension Test.
6.1.1 Requirements—The material as represented by tension test specimens shall conform to the requirements prescribed in
Table 2.
6.1.2 Number of Tests—One test specimen shall be taken from each end of every coil.
6.1.3 Test Method—The tension test shall be made in accordance with Test Methods and Definitions A370, except that the length
L for evaluation of the elongation shall be calculated from the following formula:
L 5 11.3=W·T
where
W = width of the wire, and
T = thickness of the wire.
