Surface Condition

The surface of the wire as received shall be smooth and have a uniform finish suitable for coiling or shaping the various types of springs. No serious die marks, scratches, or seams may be present.
The wire shall be properly cast. To test for cast, a few convolutions of wire shall be cut from the coil and allowed to fall on a flat surface. The wire shall lie substantially flat on itself and shall not spring up and show a wavy condition.
Each coil shall be one continuous length of wire,properly coiled. Welds made prior to cold drawing are permitted. Weld areas need not meet the mechanical requirements of this specification.

Ordering Information

Orders for material under this specification should include the following information for each ordered item:
Quantity (weight),
Name of material (name of specific type required)
Packaging, marking, and loading
ASTM designation and date of issue, and
Heat (cast) analysis (if desired).

Manufacture Process

wire drawn to size by cold deformation of a starting material that has been subjected to a thermal treatment of patenting, giving structure suitable for subsequent rolling or drawing.
1 The steel shall be made by any of the following processes: open-hearth, basic-oxygen, or electric-furnace.
2 A sufficient discard shall be made to ensure freedom from injurious piping and undue segregation.
3 The wire shall be cold-drawn to produce the desired mechanical properties

For the manufacture of the following types of upholstery springs:

1.1.1 Type A—Coiled (Marshall pack),
1.1.2 Type B—Coiled and knotted,
1.1.3 Type C—Coiled and knotted (offset style),
1.1.4 Type D—Coiled and hooked (single and cross helicals),
1.1.5 Type E—Coiled and hooked (short tension—regular tensile strength),
1.1.6 Type F—Coiled and hooked (short tension—high tensile strength),
1.1.7 Type G—Regular lacing,
1.1.8 Type H—Automatic lacing,
1.1.9 Type I—Zig-zag (U-formed),
1.1.10 Type J—Square-formed, and
1.1.11 Type K—Sinuous for furniture spring units.

Packaging, Marking, and Loading

Packaging of the coils of wire shall be by agreement between the producer and the purchaser. This agreement shall include coil dimensions and weights.
When specified, the packaging, marking, and loading shall be in accordance with Practices A700.
Marking shall be by a tag securely attached to each coil of wire and shall show the identity of the producer, size of the wire, type, and ASTM specification designation.
Bar Coding—In addition to the previously-stated identification requirements, bar coding is acceptable as a supplementary identification method. Bar coding should be consistent with AIAG Standard AIAGB-5 02.00, Primary Metals Identification Tag Application. The bar code may be applied to a substantially affixed tag.
