The continuous increase in the demand for electricity, the need to increase the power and of power units, efficiency causes the development and researches of dedicated materials. These materials work in extremely harsh conditions, they must be resistant to high temperatures, sudden changes of temperature and deformation. They are also exposed to fatigue damage both mechanical and thermal. The steel grade presented in this paper is a boiler steel working in temperature ranges 500-600 ºC. Important parameters for steels of this type are high temperature mechanical properties. It is also important that a high level of properties is achieved at both elevated and room temperatures. Elements working in such conditions, including the steam turbine armour, are exposed to thermal shock what will be presented in this paper.Keywords: Thermal shock, high temperature parameters, cracking
