SWRH62B Patented Spring Steel Wire Drawing condition

All cold drawn spring wire is commonly shaped by drawing. A distinction as to the method of drawing can be

made between:

1 dry drawn (d): drawn through pulverized lubricants such as soap, stearates or similar substances;

2 paste drawn (ps): drawn through very viscous greases of mineral oil base, tallow, synthetic waxes or similar substances;

3 gray bright (gr): drawn through rape oil, thin-bodied mineral oils or similar substances;

4 wet drawn (w): drawn through aqueous emulsions of greases or oil emulsions;

5 liquor finished (l): drawn through aqueous solutions with or without addition of metal salts.


SWRH62B Patented Spring Steel Wire 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.


SWRH62B Patented Spring Steel Wire Coating and surface finish

The spring wire may be supplied phosphate coated (ph) either dry drawn or wet drawn, copper coated (cu), zinc (Z) or zinc/aluminium (ZA) coated.

Other coatings, considered as special, can be agreed between the purchaser and the supplier. If no specific surface finish is specified, the type of finish shall be at the manufacturers discretion. In addition the wire can be ordered with an oiled surface for all surface finishes.


The term “patented wire” refers to a particular process through which steel wire is strengthened to particular specifications, rather than an actual type of wire. Sometimes called “improved plow steel” or “extra improved plow steel” wire, patented wire is high-carbon, high-tensile steel wire that has been put through a special heat-treatment process for added durability and strength. For this reason, patented wire is popular for use in the manufacturing of wire rope, music wire and high tensile spring applications. Patented wire can be made to a variety of hardness levels, depending mainly on the carbon level in the steel prior to quenching. It is also available in a variety of diameter sizes.


SWRH62B Patented Spring Steel Wire Surface quality

The surface of the wire shall be smooth and as free as possible from grooves, tears, rust and other surface defects, which have a noticeable adverse effect on the application of the wire.

In the case of zinc or zinc/aluminium coated spring wire the amount of zinc or zinc/aluminium on the wire surface shall satisfy the minimum values specified


Patented Wire is a standard grade music wire that has been conditioned for spring and wire rope applications where strength and high tensile are needed. Patenting is a heat treatment process that improves the durability and strength of the wire. The process involves an in-line heat treatment at 970 degrees Fahrenheit and then cooled in a variety of mediums including air and lead.


Information to be supplied by the purchaser

The purchaser shall clearly state in his enquiry or order the product and following information:

a) the desired quantity;

b) the term spring steel wire or straightened and cut lengths;

c) the number of this European standard: JIS G3521;

d) the steel grade

e) the nominal wire diameter selected from Table 3 and for cut length the length and the length tolerance class

f) the coating indicated by its abbreviation and surface finish

g) the form of delivery and unit mass

h) the type of inspection document;

i) any particular agreement


SWRH62B Patented Spring Steel Wire Out of roundness

The difference between the maximum and minimum diameter of the wire at the same cross section shall not be more than 50 % of the total permissible deviation specified


SWRH62B Patented Spring Steel Wire Marking and packaging

Each unit shall be properly marked and identified so as to permit traceability and reference to the inspection documents.

The labels shall withstand normal handling and contact with oil; they shall show the information according to JIS G3521. Other information shall be the subject of an arrangement between the parties.

Wire shipments shall be suitably protected against mechanical damage and/or contamination during transport.
