|Publication Date:||29 October 1973|
|ICS Code (Steels for reinforcement of concrete):||77.140.15|
This specification covers three classes of uncoated, high-strength, hard-drawn steel wire for use in the manufacture of prestressed concrete pipe.2 In application, the wire is helically wrapped on the pipe maintaining tension by mechanical means not including drawing dies.
Note-The values stated in inch-pound units are to be regarded as the standards.
2 Prior to the issuances of this specification it was common practice in the prestress concrete pipe industry to refer to the requirements of specification A227, for Steel Wire, Hard-Drawn for mechanical Springs. See the Annual book of ASTM Standards, Parts 3 and 5.
