Material description for spring wire

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 , for example, subjected to very high temperatures, over +120 degrees, stainless steel spring wire is beneficial, as it can tolerate higher temperatures.
