. "Super 304H is an austenitic steel which is mainly used for boilers in thermal power plants and the energy sector. Strength at high temperatures has become one of the most important attributes in the design of boiler tubes. The differences in material properties, especially in its creep resistance compared to other austenitic steels of similar composition, are mainly achieved by the addition of about 3 wt.-% of copper. The formation of fine Cu-rich precipitates during manufacture leads to an increased creep strength during the process of precipitation hardening. The impact of the welding cycle on the grain coarseness in the heat affected zone (HAZ) for S304H steel will be demonstrated in this paper. The options and procedures for predicting grain size by mathematical modelling of welding and heat treatment will also be shown here. The method of acquiring the input data for the mathematical models which predict the grain size will also be described."@en . "1"^^ . . "CZ - \u010Cesk\u00E1 republika" . . . . . .
