Stainless Steel Compression Springs

Compression springs for general use. Dimensions according to international standards.

Legend:

TC = Total Coils

R = Spring Rate

Coiling: Right hand

Springs with WD ≤ 0.4 do not have ground end coils, others have 3/4 end coils ground. Springs with WD ≥ 2.0 are shot peened.


Pre-setting

Springs having a calculated high stress under load to CL are pre-set to solid length.


Material:

Lesjöfors standard compression springs are produced with different material depending on design and application.

Unalloyed spring steel:
EN 10270-1-SH
EN 10270-2-FDSiCr


Stainless spring steel:
SUS304WPB
EN10270-3-1.4310


Min load length and temperature:

Minimum load length CL applies for static or pseudo static loaded springs operating at temperature up to about 40°C for unalloyed springs and up to about 150°C for stainless steel springs.

The relaxation, i.e. the power loss over time, will then stay within acceptable values for most applications. At higher operating temperatures or dynamic life demands, more than 10,000 cycles, the spring should not be loaded as far as CL.


Maximum permitted operating temperature:

EN10270-1-SH ~120 °C
EN 10270-2-FDSiCr ~250 °C
EN10270-3-1.4310 ~250 °C
SUS304WPB ~250 °C
