Small punch testing of thickwalled pipe made of the steel P92 with heterogeneous microstructure
Original language description
The paper deals with the small punch testing of material properties including short-term creep resistance andmicrostructure analysis a thick-walled pipe made of P92 steel, where metallographic analysis revealednumerous internal defects, especially close to the inner surface of the pipe. These defects had their origin inthe shrinkage porosity of the continuously cast slab and remained in the microstructure probably due toinsufficient deformation during pipe rolling. The local material properties at the both inner and outer surfaceswere compared by metallography, tensile tests, hardness tests, Charpy-V notch tests as well as small punchand small punch creep tests. The obtained results are compared with the material requirements for P92 steeland an attempt is made to evaluate the possible influence of the inhomogeneity of the microstructure andproperties on the long-term service life of the pipe under creep conditions.
