Surface protection

Disc springs are used in many applications where corrosive media is common. When used in outdoor areas, the spring steel is attacked by condensed, rain, river and sea water.

Further applications can be found in automotive building, the food industry, household appliances (e.g. washing machine), bridge building, the aerospace industry etc.

Besides watery or chloride-containing solutions, acids and etches in various concentrations get in contact with the disc springs here.

In those cases the standard spring steels do not provide sufficient protection and need specific surface treatment to have suitable protection for the working environments.

The criteria given in the following tables are intended to help you find the surface protection best suited for your applications.
