Accelerated weldability investigations of modern high alloyed martensitic steels for ateam boiler components application

The paper provides basic information on modem high alloyed martensitic steels (over 9% Cr) suitable for high temperature application in steam boilers. Besides overview of materials and their properties (VM12, T/P 91, E911 andT/P 92), the paper deals with comparison of these materials and conventionally used X20Cr- MoV12-l steel, which was often used for high temperature application in creep sensitive and scaling corrosion sensitive range. The authors presented results on accelerated investigation of weldability of modem high alloyed martensitic steels, supported by some practical results from workshop.
