Pressure tanks with the enamel surfaces play an important role mainly in the food industry and pharmacy. As the best advantage of these enamels there is very good resistance against aggressive environment at keeping the required mechanical properties of low-alloyed steels which are used for these applications. Enameling is generally applied as several particular layers whereas every of these layers has to undergo the pre-defined temperature cycle. Because of increasing device service life there is very often applied repeated enameling. The paper deals with the monitoring influence of the temperature exposition on the change of mechanical properties and structure of the basic material P265GH regarding its initial properties. The aim was to identify whether and eventually how these repeated emailing can influence the basic material degradation and based upon this to determinate their possible maximal number.
