Standard Specification for General Requirements for Wire Rods and Coarse Round Wire, Alloy Steel
SCOPE
1.1 This specification covers general requirements for alloy steel rods and uncoated coarse round alloy wire in coils that are not required to meet hardenability band limits.
1.2 In case of conflict, the requirements in the purchase order, on the drawing, in the individual specification, and in this general specification shall prevail in the sequence named.
1.3 The values stated in inch-pound units are to be regarded as the standard.
