Untempered-carbon spring steel flat wire is commonly supplied in a Number 2 regular bright finish. The manufacturer should be consulted if another finish is required.
Hardened and tempered spring steel flat wire is usually supplied in one of the following recognized finishes:
1 Black-tempered,
2 Scaleless-tempered,
3 Bright-tempered,
4 Tempered and polished,
5 Tempered, polished, and colored (blue or straw), and
Unless otherwise specified, flat wire is coated with oil to minimize scratching and to retard rusting in transit. If the product is not to be oiled, it must be so specified.

Number 1 Edge is a prepared edge of a specified contour (round or square) which is produced when a very accurate width is required or when the finish of the edge suitable for electroplating is required, or both.
Number 2 Edge is not applicable to flat wire products.
Number 3 Edge is an approximately square edge produced by slitting.
Number 4 Edge is a rounded edge produced either by edge rolling or resulting from the flat rolling ofa round section. Width tolerance and edge condition are not as exacting as for a No. 1 Edge.
Number 5 Edge is an approximately square edge produced from slit–edge material on which the burr is eliminated by rolling or filing.
Number 6 Edge is a square edge produced by edge rolling when the width tolerance and edge condition are not as exacting as for No. 1 Edge.

Orders for material to this specification shall include the following information, as necessary, to describe adequately the
desired product:

2 Name of material (flat wire identified by type),
3 Analysis or grade, if required
4 Temper of low carbon or type of spring steel
5 Edge
6 Finish or coating
7 Dimensions,
8 Coil type and size requirements
9 Packaging
10 Condition (oiled or not oiled)
11 ASTM designation and date of issue,
12 Copper-bearing steel, if required,

14 Case or heat analysis (request, if desired), and
15 Exceptions to the specification, if required.
Carbon spring steel flat wire is produced to a carbon range in which the specified or required maximum is over 0.25 % by cast or heat analysis. Two types of carbon spring steel flat wire are produced:
1 Untempered cold-rolled carbon spring steel flat wire, produced to several desirable combinations of properties
2 Hardened and tempered carbon spring steel wire.
Flat wire is generally produced from hot-rolled rods or round wire, by one or more cold-rolling operations, primarily for the purpose of obtaining the size and section desired and for improving surface finish, dimensional accuracy, and varying mechanical properties. Flat wire can also be produced from slitting hot- or cold-rolled flat steel to the desired width. The hot-rolled slit flat steel is subsequently cold reduced. The width to thickness ratio and the specified type of edge generally determine the process that is necessary to produce a specific flat-wire item. The production of good surface quality flat wire is dependent upon scale-free and clean wire, rod, or hot-rolled steel prior to cold-rolling. Scale removal can be accomplished by chemical or mechanical cleaning.
Flat wire is prepared for shipment in a number of ways. The material may be bare, paper or burlap wrapped, boxed, skidded or palletized, skidded and shrouded, palletized and shrouded, barrelled, or a combination thereof. The purchaser should specify the method desired. When coils are ordered it should be specified whether a ribbon or tape wound or a vibrated coil is desired. Since coil diameters and weights vary by the manufacturers, the manufacturer should be consulted for specific capability and limitations. When coil weight is specified for low-carbon steel flat wire or for untempered-carbon spring steel flat wire, it is common practice to ship not more than 10 % of the total weight of an item in short coils, which are those weighing between 25 and 75 % of the maximum coil weight.
