 Material
» Round wire
Carbon steel and stainless steel are the material most used for
springs production.
- Carbon steel used for static and dynamic springs according to
UNI EN 10270/1 (we can also use pre-galvanizing material).
- Stainless steel used for springs which work in adverse environments
according to UNI EN 10270/3.
For particular uses we can employ alloys, such as brass,
bronze and copper according to UNI EN 1216,
or material such iron or zincplating iron.
» Strip whit round edges
The flat strip is obtained from round wire that doesn’t
need hardening but only tempering and so it is used in several applications.
We can use carbon steel according to UNI
EN 10016 or stainless steel according to UNI
EN 10270/3.
» Strip
Annealed material is used for components with particular shapes
and bends, with shearings or other workings.
This is an ideal material to be wrought/processed and can become/ becomes
very strong after being hardened.
In case of simple springs we can also use already/previously
hardened materials, such as the blue tape.
UNI EN 10132/4 is the reference for
carbon steel, while the stainless steels make reference to UNI
EN 10088-2.
