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

 

SWRH42B Hard Drawn Spring Steel Wire 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.

Patenting HEAT TREATMENT consisting of AUSTENITIZING followed by COOLING under conditions suitable for producing the appropriate structures for subsequent wire-drawing or rolling. The medium in which the PATENTING takes place should be specified, for example air, lead bath etc.

 

Spring wire is a product with very specific technology. It has a strong structure and a good balance of flexibility and tensile strength. According to different surface treatments, spring wire can be divided into: Hot-dipped galvanized wire, electro-galvanized spring wire and PVC coated spring wire. In addition, we also provide stainless steel spring. In the mattress industry, spring wire is used to manufacture springs and hoops. In the Springs' industry, spring wire is used to manufacture mechanical springs. For other usages, our products also have gained a good reputation from the appliance as controlling cable or connecting wire for automobile industry and hard needle.

 

Spring steel is an alloy that can withstand intense twisting and bending without becoming distorted. It is resilient and pliable, yet durable, which is perfect for a general use steel. Products made with this alloy can be bent, extended, compressed, or twisted, yet they will return to their original shape. This characteristic is commonly known as high yield strength. Spring steel’s high yield strength is achieved through one of two manufacturing processes: (1) Hardening by heat treatment and (2) Work hardening. There are many different types of spring steel. They may be identified by their steel grade, which is determined by a material’s chemical, physical, and environmental properties. They may also be identified by their application, such as compression, torsion, or tension.

 

SWRH42B Hard Drawn 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.

 

Hard-drawn springs wire are affordable, flexible, and reliable carbon steel wire designed to withstand static loads and consistent stress. Also called cold-drawn spring steel, this wire type is manufactured to a specific diameter without additional tempering or processing. Improve your application with hard-drawn wire from Fushun. We're ISO 9001:2008-certified spring manufacturer dedicated to supplying our customers with high-performance spring products on time and at a competitive price. Hard-drawn spring steel wire, or HDMB spring wire, is manufactured using a cold-drawing process. During this activity, the wire being worked is coated in oil and pulled through one or more dies to reduce the wire width. One of the most economical and versatile steel wire types, hard-drawn wire is perfect for a range of general-purpose applications.

 

SWRH42B Hard Drawn Spring Steel Wire Surface treatment

The surface for spring wire generally has a coating for facilitating wire drawing and spring forming.

Exceptionally the material will be uncoated. Common surface coatings are:

1 bright (b): without any special coating: standard borax coating or lime-coating may be applied;

2 phosphate coated (ph): the wire has been treated in a solution to form a metal-phosphate layer on the surface;

3 reddish (rd): the surface is covered with a thin copper, generally a conversion coating;

4 copper plated (cu): the surface is covered with a (uniform) thick copper coating;

5 galvanised (Z): the surface is covered with a zinc coating;

6 zinc/aluminium coated (ZA): the surface is covered with a Zn 95/Al 5 coating;

7 yellow coated (y): this applies only to liquor finished products whereby a mixture of tin salts and copper salts are added at the liquor finishing;

8 white (liquor finished) (wh): this applies to liquor finished products whereby tin salts are added for liquor finishing

 

SWRH42B Hard Drawn 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

 

SWRH42B Hard Drawn 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

 

SWRH42B Hard Drawn 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.
