(Specification)Standard Specification for Steel Wire, Hard-Drawn for Prestressed Concrete Pipe
Standard Specification for Steel Wire, Hard-Drawn for Prestressed Concrete Pipe
ABSTRACT
This specification covers two classes of uncoated, high-strength, hard-drawn steel wires for use in the manufacture of prestressed concrete pipe. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process, and shall be free of injurious piping and undue segregation. The wire shall be cold drawn to produce the desired mechanical properties and there shall be no welds or joints in the finished wire. Cast or heat analysis of the steel shall conform to the chemical requirements specified for carbon, manganese, phosphorus, sulfur, silicon, and nitrogen. The tension and relaxation tests shall conform to the specified tensile requirements including tensile strength and breaking strength. Torsion test shall also be performed where test specimens shall be inspected for primary break shear area and longitudinal (spiral) splitting following completion of the test.
SCOPE
1.1 This specification covers two classes of uncoated, high-strength, hard-drawn steel wire for use in the manufacture of prestressed concrete pipe. In application, the wire is helically wrapped on the pipe maintaining tension by mechanical means not including drawing dies.
1.2 A supplementary requirement (S1) is provided for use where hydrogen embrittlement (HE) resistance testing is required by the purchaser. Supplementary requirement (S1), which establishes acceptance criteria for HE resistance testing, applies only when specified in the purchase order or contract.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 The following caveat pertains only to the test method portions of this specification, 6.3.3 and 6.5.3: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.

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.
