The work is focused on evaluation of resistance of the welded joint made of supermartensitic 13Cr6Ni2.5Mo stainlesssteel to sulfide stress cracking. Testing method A and solution B in accordance with NACE TM 0177 were used. All the testingsamples were ruptured in a very short time interval but welded joint samples were fractured primarily in the weld metal or inheat affected zone and not in the basic material. Material analysis of samples were made with use of a ZEISS NEOPHOT 32light microscope and a JEOL 6490LV scanning electron microscope.
