Material
DIN 17224 AISI 302 WERKSTOFF NO. 1.4310
Working temperature between -200 ºC and +250 ºC.
Produced in stainless steel for use in all environment. The stainless steel is rust-resistant.
Calculation of spring force
Fn for stainless steel spring steel is approx. 0.88 x Fn for music wire.
Calculation of spring force at a given length is travel s * R
If compression springs with a very high spring constant/carrying capacity are required, coloured die springs are recommended.
Winding direction
Normally right-handed
Misc.
If the springs are compressed to Ln, the spring will set itself. It will then not return to its original length, L0.
Always dimension a spring so that it delivers the desired travel and force with as little exertion as possible. This prolongs the service life of the spring. Applying maximum load to the spring will shorten its service life and cause it to become permanently distorted.
