Which spring steel sheet and surface treatment, with their specific properties, is suitable for which spring technology application. And which surface treatments or coatings are used to obtain which additional properties in the form of corrosion protection, electrical conductivity, medical purity, gliding properties … for the required shaped spring, flat spring, leaf spring, spring clip, stamped and bent part, contact spring or laser part.

The following tabular overview shows a selection support for the suitable spring steel sheet or the optimum surface treatment. Below you can see how well the spring steel grade or the surface treatment is basically unsuitable (-), low (G), medium (M) or very good (H) for which application and property.
