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.

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.
