Solfer® CA
Solfer® CA introduction
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.
