Name ofmaterial (cold-drawn steel mechanical spring wire) and class
Wire diameter
Packaging
Cast or heat analysis report, if requested
Certification or test report, or both, if specifiedand
ASTM designation and date of issue
Manufacture Process
The steel may be made by any commercially accepted steel-making process. The steel may be either ingot cast or strand cast.
The finished wire shall be free of detrimental pipe and undue segregation.
The wire shall be cold drawn to produce the desired mechanical properties
Surface Condition:
The surface of the wire as-received shall be free of rust, excessive scale, die marks, pits and scratches detrimental to the end application. Seams shall not exceed 3.5 % of the wire diameter or 0.25 mm [0.010 in.], whichever is less.
Location of Test—Test specimens shall be taken from either or both ends of the coil.
Form of delivery
The wire shall be delivered in unit packages of a coil (singles, carriers or formers), spools, spoolless cores or as straight lengths. Unless otherwise agreed at the time of ordering, the form of delivery will be coils; straight lengths shall be supplied in bundles.
Packaging, Marking, and Loading for Shipment
The coil mass, dimensions, and the method of packaging shall be agreed upon between the manufacturer and purchaser.
