The paper reports on the study of the influence of cooler type on structure and hardness of a pearlitic-ferritic grey cast iron. Five types of coolers were utilized: steel, cast iron, titanium, copper and aluminium coated with a 2 mm steel layer. White iron consisting of very fine ledeburite is obtained in the contact area with the cooler. The cooler type influences the thickness of the white iron layer generated next to it. On the other hand it does not influence type and dispersion of the structure and the maximum hardness obtained at the surface of the casting (in contact with the cooler). Conclusions are drawn related to the possibility and necessity of utilizing non-ferrous metal coolers of high thermal conductivity [ABSTRACT FROM AUTHOR]
