Contact Disc NFE 25-511 M spring steel mechanically galvanized 8,2/18/1,4

Spring steel is a steel that has a higher strength compared to other steels, but with very high elasticity. Tension discs and disc springs are made of spring steel so that the spring forces defined in the standard can be achieved.

Zinc flake coatings are non-electrolytically applied coatings in accordance with DIN EN ISO 10683. Additional top coats and lubricants may be applied. As this is a non-electrolytic process, no hydrogen is produced which could cause the components to become brittle. This requires correct pre-treatment. The corrosion protection is 10 times greater than that provided by electroplated coatings of the same thickness.
