Pearlitizing is mainly used on cast iron workpieces in order to produce a fully or partially pearlitic microstructure, thereby improving strength, and, if necessary, to bring about an equalization of material properties in the case of different material thicknesses (and thus different cooling times during production).<\/p>\n\n

\n
\n

In the first step, the workpiece is annealed between 850 and 920 \u00b0C to achieve austenitization (carbon saturation) of the microstructure, for which a holding time of one hour is usually sufficient.In the second step, cooling takes place in still or moving air. The decisive factor here is the correct cooling rate, which must not be too slow in order to avoid ferritization, but also not too fast in order to prevent the formation of hardening<\/a> microstructures (martensite) (which, after all, is specifically brought about in hardening by rapid quenching). <\/p>\n\n\n\n

Once the perlite formation process is complete, stress relief annealing<\/a> often takes place immediately (before the material has cooled down completely) in order to reduce the risk of cracking in delicate components and to save energy. <\/p>\n<\/div>\n\n\n\n
