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.

A tag shall be securely attached to each coil of wire with identifying information as agreed upon by the purchaser and manufacturer.

Unless otherwise specified in the purchasers order, packaging, marking, and loading for shipments shall be in accordance with those procedures recommended by Practices A700.

Our spring steel wire comes in various categories such as music wire, hard drawn wire, oil tempered wire, chrome silicon wire, chrome vanadium wire, stainless steel wire, nickel plated wire, phosphate coated wire, galvanized wire, and copper coated wire.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
