Modified 2.25Cr1Mo steel, known as a relatively new
generation, grade T24 heat resistant steel (7CrMoVTiB10-
10), is extensively used as a material for fabrication of water
walls panels - evaporator tubes in supercritical boilers of a
new generation in thermal power plants. A special
advantage of T24 steel is low carbon content and the
optimal content of alloying element which simultaneously
provides its good weldability and heat resistance. For
elements up to 10 mm of thickness, made of T24 steel
standards not foreseen previous and subsequent post-weld
heat treatment (PWHT). However, after a series of problems
encountered with welded joints, practice has shown that
some kind of heat treatment is necessary, in order to reduce
the susceptibility to hydrogen induced stress corrosion
cracking (HISCC). This paper deals with the microstructural
characterization of both base material and welded joint of
boiler tube (dimension �����44,5x7,1 mm), made of T24 steel,
before and ...after PWHT. The aim of this paper is to evaluate
the effect of this type of PWHT on microstructural changes
and its possible impact on the susceptibility to cracking of
T24 welded joints.
