Other materials like Inconel, Incoloy HT800, copper beryllum and spring bronze are available on request.
Squared and Ground Ends
0C... are squared and ground from wire diameter d=0,50.
0X... are squared and ground from wire diameter d=0,50.
0D... are squared and ground from wire diameter d=1,00.
Surfaces
Compression springs made of the material 1.1200 spring steel are oiled.
Compression springs mades of the material 1.4310 are dry.
Winding Direction
The standard winding direction of compression springs is right hand winding. This means that if you look through the spring axis, the winding of a spring wound to the right moves away clockwise.

Service Life
The actual service life of a compression spring depends, among other things, on the spring deflection between the two compression points and their position relative to the spring length. Thus, the service life will differ for each spring.
