Material description for spring wire

Here's an overview of the most popular types of spring wire.

Examples illustrating the use of different wire variants:

Piano wire - springs that are mounted indoors in a stable environment without damp or high temperatures. This spring wire is not rust-proof.

Stainless steel spring wire - used e.g. for high temperatures, in damp environments and in the food industry.

Pre-galvanised spring wire - if the spring is used outdoors or in damp environments, pre-galvanised wire is useful.

Electro-galvanised spring wire - if the spring is to be shiny, a spring made of piano wire can be subsequently electro-galvanised. This surface is shiny and offers a limited degree of rust protection. Please note that the electro-galvanisation process can cause acid brittleness in the wire.

Hastelloy and Inconel - if the spring is to be used in the offshore industry, an acid-proof, corrosion-resistant material is chosen. This might be Hastelloy or Inconel. Hastelloy and Inconel are more precious materials that are less commonly seen.

Temperatures - if the spring is subjected to very high temperatures, over +120 degrees, stainless steel spring wire is beneficial, as it can tolerate higher temperatures.

The online shop has various spring wire types, from 0.20 mm to 5.00 mm in wire diameter.

Other alloys, lengths and sizes of spring wire can be ordered to your own specification in cooperation with our technical department.
