Description

Solfer® grades are obtained by decarburisation.

Decarburisation during open-coil annealing process – Solfer® and Solfer®+ grades: these grades are particularly suitable for the direct-on white or coloured enamelling process after degreasing, pickling and deposition of a nickel layer. However, they can also be used for two-coat / one-fire or for ground enamelling processes using ground-coat enamel specially designed for the low intrinsic reactivity of these grades (e.g. enamelling of self-cleaning pyrolytic oven cavities

Solfer® and Solfer®+ grades are suitable for the manufacture of complex parts (medium to deep drawing) and are compatible with all existing enamelling processes (direct-on white or coloured enamelling after degreasing, pickling and coating with nickel, two-coat / one-fire or ground enamelling after degreasing), with enamel layers being applied as either a liquid or a powder. These grades offer 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	Direct-on enamelling process: Solfer® and Solfer®+ grades Surface preparation: Surface preparation before enamelling must be performed with the greatest care (degreasing, pickling and coating with nickel). This is essential to achieve a good surface appearance of the part after enamelling and good adhesion of the enamel. The level of iron loss after pickling and the quantity of nickel deposited must therefore be monitored very precisely. Application of the enamel and firing: The thickness of the enamel layer deposited is generally about 130 microns. Moreover, Solfer® and Solfer®+ grades are compatible with all the common enamelling processes: wet spraying, electrostatic liquid or powder deposition. Taking into account its limited Al content, the Solfer® grade is particularly suitable for the ETE application process. 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. 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.
Processing methods	Solfer® grades can be formed by bending, profiling or deep drawing.
