1.4310 Stainless Steel Wire

What is 1.4310?

1.4310 is essentially a leaner version of 1.4301, which as a result of its combination of high chromium and restricted nickel content, produces a metastable austenitic structure which will work harden / strengthen very rapidly when subjected to cold deformation. Since this steel is used for the production of spring components, the final microstructure will contain a significant amount of shear induced martensite and as such will be relatively magnetic.

1.4310 Stainless Wire Chemical composition

1.4310 Stainless Equivalent

1.4310 Stainless Wire Form of delivery

The wire shall be supplied in coils, on spools, on spoolless cores or carriers. Several coils may be assembled on a carrier. Unless otherwise specified the form of delivery shall be at the manufacturer's discretion. They shall however inform the purchaser about the form of delivery. Wire in straight lengths is normally supplied in bundles.

1.4310 Stainless Wire Surface finish

The wire may be coated or not. The specific coating and finish for stainless steel spring wire shall be agreed upon at the time of enquiry and order- e.g. uncoated, polished finish, nickel coated.

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: EN 10270-3;

d) the steel grade and for grade 1.4301, 1.4310 and 1.4462 also the tensile strength level

e) the nominal wire diameter and for cut length the length and the length tolerance class

f) the surface finish

g) the form of delivery

h) the type of inspection document to be supplied

i) any particular agreement made.

1.4310 Stainless Wire Manufacturing process

Unless otherwise agreed in the order, the manufacturing process used in the making of the stainless steel wire is left to the discretion of the manufacturer. The starting condition (+AT:solution annealed) of the wire (rod) is specified in EN 10088-3.

1.4310 Stainless Wire Surface quality

The surface of the wire shall be as far as practically possible free from grooves, pits and other surface defects, which could impair proper use of the wire. One method to reveal surface discontinuities is the reverse torsion test

In cases where the wire is intended for high-duty springs, the purchaser and the supplier may agree at the time of order about special surface requirements and tests.

1.4310 Stainless Wire Inner soundness

The wire shall be sound and free from any inhomogenity or defect which significantly limits its use. Tests appropriate for an assessment of the inner soundness of the wire, such as the wrapping test, may be agreed upon at the time of ordering.

1.4310 Stainless Wire Introduce

1.4310 stainless steels are usually used in the cold drawn condition in the form of wire of circular cross-section up to 10,00 mm in diameter, for the production of springs and spring parts that are exposed to corrosive effects and sometimes to slightly increased temperatures.

1.4571,1.4539,1.4028 are also used for springs,although to much lesser extent. In these cases the mechanical properties(tensile strength, etc.)should be agreed between purchaser and supplier. Similarly, diameters between 10,00 mm and 15,00 mm may be ordered against this standard; in this case the parties should agree upon the required mechanical characteristics.

1.4310 Stainless Wire Marking and packaging

Each unit shall be properly marked and identified so as to permit identification, traceability and reference to the inspection documents. The labels shall withstand normal handling and show the information according to EN 10270-3. Other information shall be subject of an agreement between the parties.

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