Weldability of modern low alloyed steels for elevated temperature application in steamboiler components production

The paper presents basic materials for application in steam boilers at elevated temperatures. Special emphasize is given on low alloyed Cr-Mo steels predicted for elevated tem¬peratures application. In that sense, the weldability of modem T/P 23 and T/P24 steels is explained and supported with results of practical experiences. Besides appropriate main welding parameters, in research into weldability of these steels it is important to determine preheating and interpass tempera¬ture, as well as parameters of post weld heat treatment. Properties of relatively new developed low alloyed steels are compared with conventional T/P 22 steel (13CrMo4-5).
