Description

Solfer® grades are obtained by decarburisation.

Surface decarburisation during continuous annealing process – Solfer® CA grade: this patented steel grade has been developed for the two-coat / one-fire enamelling process. Nevertheless, it can also be used for ground or conventional enamelling processes.

Solfer® CA grade is suitable for light to medium drawing and is compatible, after degreasing, with the two-coat / one-fire enamelling process using the wet/dry or dry/dry method. This grade can also be used for the ground enamelling process. It offers excellent resistance to "fish scale" defects. A minimum TH of 100 is guaranteed, in accordance with EN 10209:2013.

Surface appearance after enamelling is excellent: no pinholes or black spots. This is linked to the ultra-low carbon content of these grades (throughout for Solfer® and Solfer®+ grades and on the surface for Solfer® CA grade). Moreover, for Solfer® and Solfer®+ grades, deformation at high temperature (e.g. sagging, during pyrolytic cycles) is limited.

Technological properties

Property
Application areas	Solfer® grades are particularly suitable for the manufacture of casing panels for domestic appliances (hobs, covers, control panels, side panels etc) and for kitchen utensils (pots and pans). They can also be used for architectural applications, thanks to their excellent resistance to deformation during enamel firing.
Chemical composition	The manufacturing conditions guarantee very good resistance to "fish scale” defects (TH > 100 in accordance with EN 10209:2013).
Coating	Two-coat / one-fire enamelling process: Solfer® CA, Solfer® and Solfer®+ grades Surface preparation: Very meticulous degreasing before enamel application is essential Enamel application and firing: Solfer® grades are compatible with all the common enamelling processes: wet spraying, electrostatic liquid or powder deposition. It is essential that the following requirements are met: Use of ground-coat enamel containing a high level of metallic adhesion oxides The thickness of the ground-coat enamel should not be less than 35 microns or more than 45 microns The thickness of the cover-coat enamel should be about 100 microns Where wet application is used, it is imperative to dry the enamel layer before firing Finally, firing is performed at a temperature of about 830°C
Joining	Solfer® grades can easily be welded, whatever the welding process may be. Other joining processes (clinching, crimping) may also be used.
Other	Solfer® CA: mechanical properties as well as fish scale resistance comply with EN 10209:2013.
Processing methods	Solfer® grades can be formed by bending, profiling or deep drawing.
