SWRH57B Hard Drawn 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.

 

SWRH57B Hard Drawn 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.

 

SWRH57B 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.

 

SWRH57B 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

 

SWRH57B 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

 

SWRH57B 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

 

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.

 

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.

 

High-carbon spring steels are the most commonly used of all springs materials. They will meet your spring steel material specification in preference to others, despite being the least expensive. High Carbon spring wires are readily available, easily worked, and most popular. These materials are not satisfactory for high or low temperatures or for shock or impact loading.

 

SWRH57B 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.
